The bottleneck in communication through wireline and wireless links eventually limits the system performance. Wireline transmission at tens of Gb/s through a band-limited channel causes significant loss of signal amplitude with a long tail of post-cursors, hence requiring multi-level signaling and non-trivial equalization schemes at the cost of a large power consumption. In wireless communication, a low-noise frequency generator is an essential part as it provides the carrier for the communication. Our research in this area covers developing circuits for high-speed links and phase-locked loops.

- High-speed serial/parallel links

- Clock data recovery circuits

- Phase-locked loops for 5G and beyond
