Interfacing Resonant Sensors using Ringdown Measurement

The transient ring-down of resonant sensors is used to extract information about the sensor's resonance frequency and quality factor in a highly energy-efficient manner.

  3. An Energy-Efficient 3.7nV/√Hz Bridge-Readout IC with a Stable Bridge Offset Compensation Scheme
    H. Jiang; S. Nihtianov; K.A.A. Makinwa;
    IEEE Journal of Solid-State Circuits,
    Volume 53, pp. 856-864, 3 2019. DOI: 10.1109/JSSC.2018.2885556
    Abstract: ... This paper describes an energy-efficient bridge readout IC (ROIC), which consists of a capacitively coupled instrumentation amplifier (CCIA) that drives a continuous-time delta-sigma modulator (CTΔΣM). By exploiting the CCIA's ability to block dc common-mode voltages, the bridge's bias voltage may exceed the ROIC's supply voltage, allowing these voltages to be independently optimized. Since bridge output is typically much smaller than bridge offset, a digital to analog converter (DAC) is used to compensate this offset before amplification and thus increase the CCIA's useful dynamic range. Bridge loading is reduced by using a dual-path positive feedback scheme to boost the CCIA's input impedance. Furthermore, the CCIA's output is gated to avoid digitizing its output spikes, which would otherwise limit the ROIC's linearity and stability. The ROIC achieves an input-referred noise density of 3.7 nV/√Hz, a noise efficiency factor (NEF) of 5, and a power efficiency factor (PEF) of 44, which both represent the state of the art. A pressure sensing system, built with the ROIC and a differential pressure sensor (AC4010), achieves 10.1-mPa (1ιι) resolution in a 0.5-ms conversion time. The ROIC dissipates about 30% of the system's power dissipation and contributes about 6% of its noise power. To reduce the sensor's offset drift, a temperature compensation scheme based on an external reference resistor is used. After a two-point calibration, this scheme reduces bridge offset drift by 80× over a 50 °C range.

    Volume 54, pp. 1874-1882, 7 2019. DOI: 10.1109/JSSC.2019.2907041
    Abstract: ... This paper presents a readout IC that uses an asynchronous capacitance-to-digital-converter (CDC) to digitize the capacitance of a touch sensor. A power-efficient tracking algorithm ensures that the CDC consumes negligible power consumption in the absence of touch events. To facilitate its use in wake-on-touch applications, the CDC can be periodically triggered by a co-integrated ultra-low-power relaxation oscillator. At a 38-Hz scan rate, the readout IC consumes 15 nW per touch sensor, which is the lowest reported to date.

  8. A 4.5 nV/\sqrtHz Capacitively-Coupled Continuous-Time Sigma-Delta Modulator with an Energy-Efficient Chopping Scheme

    Volume 1, pp. 18-21, 2018. DOI: 10.1109/LSSC.2018.2803447
    Abstract: ... When chopping is applied to a continuous-time sigmadelta modulator (CTΣΔM), quantization noise fold-back often occurs, leading to increased in-band noise. This can be prevented by employing a return-to-zero (RZ) digital-to-analog converter (RZ DAC) in the modulator's feedback path and arranging the chopping transitions to coincide with its RZ phases. In this letter, this technique has been extended and implemented in an energy-efficient CTΣΔM intended for the readout of Wheatstone bridge sensors. To achieve a wide common-mode input range, the modulator's summing node is implemented as an embedded capacitively coupled instrumentation amplifier which can be readily combined with a highly linear 1-bit capacitive RZ DAC. Measurements show that the proposed chopping scheme does not suffer from quantization noise fold-back and also allows a flexible choice of chopping frequency. When chopped at one-tenth of the sampling frequency, the modulator achieves 15 ppm INL, 4.5 nV/√Hz input-referred noise and a state-of-the-art noise efficiency factor of 6.1.

  9. MEMS for biofuel composition measurement based on thermal impedance spectroscopy

    Volume 277, pp. 281--288, December 2018. DOI: 10.1016/j.snb.2018.08.098
    Abstract: ... Continuous monitoring of the composition of E85 biofuel is essential for a quick start and clean and efficient operation of Flex-Fuel Vehicles. The actual ethanol concentration in E85 fuel is in the range 50%–85% and fuel-line sensors are used for ethanol-gasoline composition measurement. However, also a small amount of water is typically present, which cannot be reliably detected using state-of-the-art capacitive fuel-line sensors. Thermal impedance spectroscopy has been investigated as a non-destructive technique to determine the composition of ternary mixtures of biofuels. The principle of the thermal conductivity detector has been extended for measuring both the thermal conductivity and the thermal capacity of biofuel in the range up to 10 kHz using an AC-operated polysilicon heater for injecting a sinusoidal heat flux, and another polysilicon strip at a well-defined spacing or thermopile sensors for measuring the in-phase and quadrature components of the resulting AC temperature difference. Measurements on the components are in reasonable agreement with simulations, with a −3 dB cut-off frequency at 422.5 Hz and 340.8 Hz for ethanol and gasoline, respectively. However, the cut-off frequency of water was found to be significantly lower than simulations due to its high surface tension, thus limiting access to the detector.

    Abstract: ... This paper presents a direct digital converter for Wheatstone bridge sensors, which is realized with commercial off-the-shelf components. The power efficiency of the readout is enhanced by embedding the bridge sensor in a second-order continuous-time sigma-delta modulator (CTDeltaSigmaM). By directly digitizing the output signal of a Wheatstone bridge in the current mode, the noise performance is dominated by the operational amplifier in the first integrator and the bridge sensor. To demonstrate the performance of the proposed circuit, an MEMS piezoresistive differential pressure sensor is used. Measurement results show that a resolution of 12.7 mParms (0.41 mOhmrms), with a 0.5-ms conversion time, can be achieved. Powered by 5 V, the circuit and the bridge sensor draw 9.55 and 7.58 mW, respectively.

  27. A 30-ppm <80 nJ Ring-Down-Based Readout Circuit for Resonant Sensors
    H. Jiang; Z. Y. Chang; M. A. P. Pertijs;
    IEEE Journal of Solid-State Circuits,
    Volume 51, Issue 1, pp. 187‒195, January 2016. DOI: 10.1109/JSSC.2015.2470552
    Abstract: ... This paper presents an energy-efficient readout circuit for micro-machined resonant sensors. It operates by briefly exciting the sensor at a frequency close to its resonance frequency, after which resonance frequency and quality factor are determined from a single ring-down transient. The circuit employs an inverter-based trans-impedance amplifier to sense the ring-down current, with a programmable feedback network to enable the readout of different resonant sensors. An inverter-based comparator with dynamically-adjusted threshold levels tracks the ring-down envelope to measure quality factor, and detects zero crossings to measure resonance frequency. The excitation frequency is dynamically adjusted to accommodate large resonance frequency shifts. Experimental results obtained with a prototype fabricated in 0.35 μm standard CMOS technology and three different SiN resonators are in good agreement with conventional impedance analysis. The prototype achieves a frequency resolution better than 30 ppm while consuming less than 80 nJ/meas from a 1.8 V supply, which is 7.8x less than the state-of-the-art.
