Outstanding TU Delft score at ISSCC 2020

This year's iteration of the world's top conference in IC design, the International Solid-State Circuit Conference (ISSCC 2020), saw the TU Delft represented by no less than 7 papers from the Department of Microelectronics - an outstanding achievement that does not even include 3 additional papers presented by former TU Delft alumni, currently affiliated with Bosch, ADI and SiTime.

ME's papers were in the following areas:

Precision Analog Circuits (Makinwa): An energy-efficient temperature sensor and an accurate frequency references, both with state-of-the-art (SOTA) performance;
Amplifiers (Fan, Pertijs, Makinwa): A class-D power amplifier (SOTA linearity and efficiency) and an amplifier for ultrasound systems with continuously variable gain (a first);
Circuits for Quantum computers (Sebastiano, Babaie): A multi-qubit controller (capable of handling 128 qubits, also a first) and a high-performance oscillator (also a first!), both operating at 4K;
Human computer interfaces (Pertijs): A chip-set that enables pen/finger-driven electronic white-boards with SOTA resolution and frame rate;

Some more stories made this event additionally special:

• The TU Delft was the largest European contributor to the conference;
• TU Delft's PhD student Jeroen van Dijk participated in the 1st ever ISSCC Quiz show!

Congratulations to all co-authors and PIs for this great collective achievement!

Student Alberto brings wireless monitoring a step closer

In September 2017 Alberto Gancedo started his master programme Microelectronics at the Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS). Alberto’s ambition was bigger than obtaining his degree. His ambition was to develop a small, portable and cheap monitoring device to detect unusual brain activity in premature babies directly after birth. Thanks to donations from EEMCS alumni, Alberto could start his master’s at TU Delft and work towards this ambition. Alberto graduated in the beginning of February 2020 and proudly updates Delft University Fund and EEMCS alumni about his achievements.
