Low-power sensor interface integrated circuit design

ESR11

Objectives

To develop a low-power sensor interface integrated circuit to read out the data sensors developed through project 9 and project 10 and to drive the micoactuators in project 8 . To save power in CMOS technology, al low supply voltage is needed, which calls for time -based design solutions. Therefore, digitally dominant analog design techniques and time-based processing will be explored to obtain an optimal circuit architecture that has state -of-the-art figure-of -merit performance. The architectural study will be followed by the actual design, fabrication, testing and validation of a sensor readout integrated circuit. Further, the test chips will be thinned down to about 15 mm in post -processing steps during secondments. The bendability of these ultra-thin chips (UTCs) will lead to improved conformability.

Expected Results

Low-power electronics interface to read the data from sensors in the skin.

Planned secondments

FBK: to define readout specifications

IMEC: to attend courses on microelectronics

UoG: to learn about thinning of Si chips

Placement

Host institution The Katholieke Universiteit Leuven

Enrolments (in Doctoral degree) The Katholieke Universiteit Leuven

Supervisors

Georges Gielen, Chris Van Hoof

Presentation of ESR11

My name is Mark Daniel Alea and I am born in Batangas, Philippines in 1992. I received my MS degree in Electrical Engineering from the University of the Philippines – Diliman in 2019. My thesis is entitled, “Gate current cancellation using replica PMOS and digital feedback for temperature coefficient reduction in ultra-low power voltage references”. From 2016 – 2020, I was an Analog IC Designer with Analog Devices Philippines where I worked on a nanogap sensor readout for biomedical applications.
