The area of my research work is Analog CMOS VLSI Circuit/System Design. Activities in my research team can be broadly classified in to two categories. The first one involves architecture development and prototype design of analog circuits/systems in three specific topics namely, Interface unit for high speed data link, On-chip DC-DC converter and Signal acquisition front-end. The second category of our work is about developing and prototyping automatable design methodologies for frequently used analog circuits/systems.
For high speed data link we have proposed a number of power efficient high speed data receivers and transmitters with active terminator. Some of our design also enables simultaneous two-way data transmission over a common link.
We have proposed a switching scheme for switched-capacitor based DC-DC converter which improves the power efficiency by 5-10%. We have proposed a scheme of dynamically adjusting switching frequency of switched-capacitor based DC-DC converter which helps to maintain high power efficiency across wide range of load current. Both, the switching scheme and switching frequency adjustment are generic enough to be applied for buck and boost converters.
