High-speed Baseband Circuits and Systems
As demands on communication networks increase, the interface between the digital and analog world becomes severely constrained. We are looking a broad range of circuit solutions to meet these challenges. Our research is studying how to use CMOS scaling to improve the speed of mixed-signal interfaces and also how to use optical techniques - in collaboration with other research groups - to leap past CMOS scaling for future the high-speed sampling.
Demonstrating the need for optical sampling for high-speeds and high-resolution quantization.
