Research

Optocoupling in CMOS (O-i-C)

In ICD group, I work on Optocoupling in CMOS in collaboration with Semiconductor Components (SC) group. In this project, we aim at designing an optocoupler in mainline CMOS process. Optocouplers transmit data using a modulated light source and receive using a photodetector. Due to absence of physical contact, they can also provide high galvanic isolation. Ability to fabricate them in a mainline CMOS process would be very cost effective.

I focus on circuit design aspects of this project. I am looking at designing driver circuits at source end and a read out circuit at receiver end. Our aim is to achieve high data rates along with high galvanic isolation.
