Understanding dark current sources in CMOS image sensors

The goal of the project would be to simulate and model the dark current in CMOS image sensors.Students interested to work on this project as part of their MTP or PhD are welcome to contact me.

Large format images for space and medical imaging

The goal of the project is to obtain large format images for space and medical applications. Students will get first hand expereince working with CMOS image sensors. Students interested to work on this project as part of their BTP or MTP are welcome to contact me.

Past Research

A Biologically Inspired CMOS Image Sensor - IMEC

Designed a biologically inspired CMOS Image sensor. A CMOS image sensor replicating the perception of vision in insects along with on-chip polarization detection ability was designed for industrial (machine vision) and medical applications.

Small Autonomous Networked Devices - Philips Research

Designed a generic sensor module architecture for SAND (Small Autonomous networked devices) project. The Project SAND was under Healthcare Devices and Instrumentation/Storage Signal Processing group of Philips Research, Eindhoven, Netherlands. It aimed to develop low power small reconfigurable modular autonomous systems, which can perform sensing/actuation functions and/or data logging, and bi-directional wireless communication.

Low Power ECG Amplifiers - Philips chair of Medical information

Design and development of low power ECG measurement devices using Texas Instruments Microprocessors. The project led to a development of micro-controller (MSP430F149) based low power ECG amplifier.

Microprocessor controlled Pacemakers - Philips chair of Medical information

Simulation of natural pacemakers with artificial ones. The project led to a development of a micro-controller (MSP430) based pacemaker controller to aid the end user.

RFID based biosensors - Insitute of Materials in Electrical Engineering, RWTH

Design of a microprocessor based RFID biosensors. Atmel's ATmega128 microprocessor was implemented to have a two-wire-interface for transfer of bio-signals to the local base station using Radio-Frequency based transponders and antennas.
