Biography

Albert J.P. Theuwissen was born in Maaseik (Belgium) on December 20, 1954. He received the degree in electrical engineering from the Catholic University of Leuven (Belgium) in 1977. His thesis work was based on the development of supporting hardware around a linear CCD image sensor.

From 1977 to 1983, his work at the ESAT laboratory of the Catholic University of Leuven focused on semiconductor technology for linear CCD image sensors. He received the Ph.D. degree in electrical engineering in 1983. His dissertation was on the implementation of transparent conductive layers as gate material in the CCD technology.

In 1983, he joined the Micro Circuits Division of the Philips Research Laboratories in Eindhoven (the Netherlands), as a member of the scientific staff. Since that time he was involved in research in the field of solid state image sensing, which resulted in the project leadership of respectively SDTV- and HDTV imagers. In 1991 he became Department Head of the division Imaging Devices, including CCD as well as CMOS solid state imaging activities.

He is author or coauthor of over 160 technical papers in the solid state imaging field and issued several patents. In 1988, 1989, 1995 and 1996 he was a member of the International Electron Devices Meeting paper selection committee. He is co editor of the IEEE Transactions on Electron Devices special issues on Solid State Image Sensors, May 1991, October 1997, January 2003 and November 2009, and of IEEE Micro special issue on Digital Imaging, Nov./Dec. 1998. In 1995, he authored a textbook "Solid State Imaging with Charge Coupled Devices" and in 2011 he co-edited the book "Single-Photon Imaging". In 1998 and 2007 he became an IEEE ED and SSCS distinguished lecturer.

He acted as general chairman of the International Image Sensor Workshop (formerly IEEE International Workshop on Charge-Coupled Devices and Advanced Image Sensors) in 1997, 2003, and 2009. He is member of the Steering Committee of the aforementioned workshop and founder of the Walter Kosonocky Award, which highlights the best paper in the field of solid-state image sensors. During several years he was a member of the technical committee of the European Solid-State Device Research Conference and of the European Solid-State Circuits Conference.

From 1999 till 2010 he was a member of the technical committee of the International Solid-State Circuits Conference. For the same conference he acted as secretary, vice-chair and chair in the European ISSCC Regional Committee and since 2002 he was a member of the overall ISSCC Executive Committee. He has been elected to be International Technical Program Chair vice-chair and chair for respectively the ISSCC 2009 and ISSCC 2010.

In March 2001, he was appointed as part-time professor at the Delft University of Technology, the Netherlands. At this University he teaches courses in solid-state imaging; coaches MSc and PhD students in their research on CMOS image sensors.

In April 2002, he joined DALSA Corp. to act as the companys Chief Technology Officer. In September 2004 he retired as CTO and became Chief Scientist of DALSA Semiconductors. After he left DALSA in September 2007, he started his own company Harvest Imaging, focusing on consulting, training, teaching and coaching in the field of solid-state imaging technology (www.harvestimaging.com).

In 2006 he co-founded (together with his peers Eric Fossum and Nobukazu Teranishi) ImageSensors, Inc. (a California non-profit public benefit company) to address the needs of the image sensor community (www.imagesensors.org).

In 2008, he received the SMPTEs Fuji Gold medal for his contributions to the research, development and education of others in the field of solid-state image capturing. He is member of editorial board of the magazine Photonics Spectra, an IEEE Fellow and member of SPIE.

In 2011 he was elected as Electronic Imaging Scientist of the Year and in 2013 he received the Exceptional Service Award of the International Image Sensor Society.

Architectures and techniques for system-on-chip imaging devices

  1. A 0.5e-rms temporal noise CMOS image sensor with Gm-Cell-Based pixel and period-controlled variable conversion gain
    X. Ge; A.J.P. Theuwissen;
    IEEE transactions on electron devices,
    Volume 64, Issue 12, pp. 5019-5026, October 2017. DOI: 10.1109/TED.2017.2759787
    Abstract: ...
    A deep subelectron temporal noise CMOS image sensor (CIS) with a Gm-cell based pixel and a correlated-double charge-domain sampling technique has been developed for photon-starved imaging applications. With the proposed technique, the CIS, which is implemented in a standard 0.18-µm CIS process, features pixel level amplification and achieves an input-referred noise of 0.5 e−rms with a correlated double sampling period of 5 µs and a row read-out time of 10 µs. The proposed structure also realizes a variable conversion gain (CG) with a period controlled method. This enables the read-out path CG and the noise-equivalent number of electrons to be programmable according to the application without any change in hardware. The experiments show that the measured CG can be tuned from 50 µV/e- to 1.6 mV/e- with a charging period from 100 ns to 4 µs. The measured characteristics of the prototype CIS are in a good agreement with expectations, demonstrating the effectiveness of the proposed techniques.

  3. Analysis and calibration of process variations for an array of temperature sensors
    S. Xie; A. Abarca; J. Markenhof; A. Theuwissen;
    conference, November 2017.
    Abstract: ...
    This paper presents an analysis and calibration of process variations for an array of temperature sensors, which are incorporated into a CMOS image sensor chip. Making use of the experimental results of more than 500 temperature sensors implemented on the same chip, the proposed calibration method has removed their process variations from 14.3 % to 2.5 % (3 sigma).

  4. Temperature sensors integrated into a CMOS image sensor
    A. Abarca; S. Xie; J. Markenhof; A. Theuwissen;
    In Proceedings of Eurosensors,
    Eurosensors, pp. 358-361, September 2017. DOI: 10.3390/proceedings1040358
    Abstract: ...
    In this work, a novel approach is presented for measuring relative temperature variations inside the pixel array of a CMOS image sensor itself. This approach can give important information when compensation for dark (current) fixed pattern noise (FPN) is needed. The test image sensor consists of pixels and temperature sensors pixels (=Tixels). The size of the Tixels is 11 μm × 11 μm. Pixels and Tixels are placed next to each other in the active imaging array and use the same readout circuits. The design and the first measurements of the combined image-temperature sensor are presented.

  5. A 0.5e- temporal noise CMOS image sensor with charge-domain CDS and period-controlled variable conversion gain
    X Ge; A Theuwissen;
    In International image sensor workshop,
    pp. 290-293, June 2017.
    Abstract: ...
    This paper introduces a proof-of-concept low-noise CMOS image sensor (CIS) intended for photon-starved imaging applications. The proposed architecture is based on a charge-sampling pixel featuring in-pixel amplification to reduce its input referred noise. With the proposed technique, the structure realizes a period-controlled variable conversion factor at pixel-level. This enables the conversion factor and the noise-equivalent number of electrons to be tunable according to the application without any change in hardware. The obtained noise performance is comparable to the state-of-the-art low noise CIS, while this work employs a simpler circuit, without suffering from dynamic range limitations. The device is fabricated in a low-cost, standard CIS process.

  6. A highly linear CMOS image sensor with digitally assisted linearity calibration method
    F. Wang; L. Han; A. Theuwissen;
    In International image sensor workshop,
    pp. 336-339, June 2017.
    Abstract: ...
    A highly linear CMOS image sensor designed in 0.18μm CMOS image sensor (CIS) technology is presented in this paper. A new type of pixel design is adopted to cancel off the nonlinearity of the source follower (SF) and hence enhance the linearity. Furthermore, a digitally assisted calibration method is proposed to improve the linearity of the image sensor. The measurement results show that the new type of pixel can achieve better linearity performance comparing with the typical 4T pixel. With the calibration, the linearity of all types of pixels have been improved.

  7. Linearity analysis of a CMOS image sensor
    F Wang; A Theuwissen;
    In Electronic Imaging,
    Electronic Imaging, Electronic Imaging, 2017. DOI: https://doi.org/10.2352/ISSN.2470-1173.2017.11.IMS
    Abstract: ...
    In this paper, we analyze the causes of the nonlinearity of a voltage-mode CMOS image sensor, including a theoretical derivation and a numerical simulation. A prototype chip designed in a 0.18 μm 1-poly 4-metal CMOS process technology is implemented to verify this analysis. The pixel array is 160 × 80 with a pitch of 15 μm, and it contains dozens of groups of pixels that have different design parameters. From the measurement results, we confirmed these factors affecting the linearity and can give guidance for a future design to realize a high linearity CMOS image sensor.

    IEEE, pp. 1-3, 2016. DOI: 10.1109/ICSENS.2016.7808589
    Abstract: ...
    This paper presents a CMOS image sensor with in-pixel nearly unity-gain pMOS transistor based source followers and optimized column-parallel amplifiers. The prototype sensor has been fabricated in a 0.18 μm CMOS process. By eliminating the body effect of the source follower transistor, the voltage gain for the pixel-level readout circuitry approaches unity. The use of a single-ended common-source cascode amplifier with ground rail regulation improves the PSRR of the column-parallel analog front-end circuitry and further the noise performance. Electrical characterization results show that the proposed pixel improves the conversion gain after the in-pixel source follower by 42% compared to that of the conventional structure. The prototype sensor with proposed readout architecture reaches a 1.1e- input-referred temporal noise with a column-level ×16 analog gain.
