Analog Mixed-Signal IC Group

Mike Chen


Our research goal is to explore the optimal analog circuit and system architecture with diminishing power and area consumption in the future nano-scale technologies. In many cases, we aim at reshaping the analog and digital boundary of the circuit/system architecture, and leveraging what technology scaling offers to address the future analog design challenges.


At the circuit level, we are interested in pushing the boundary of various critical analog mixed-signal components, such as analog-digital data converter, phase locked loop, etc. At the system level, we are also interested in wireless/wireline communication systems and emerging applications, such as bio-related, sensing systems.


We are hiring highly motivated PhD students.

We welcome Industrial/research institution collaborations.


 March 2014

Shiyu Su will present the first hybrid DAC architecture with delta-sigma assisted pre-distortion technique at VLSI Symposium 2014. This DAC achieves the new record linearity among all published high-speed (>GS/s) CMOS DACs (up to date). Congrats, Shiyu and the team!

 Dec. 2012

Dylan Hand presented a new non-uniform ADC architecture at Globecom Dec. 2012. Congrats, Dylan!

 July 2013

Praveen Sharma will present a new Nyquist VCO-based ADC architecture at CICC Sep, 2013. It achieves >400MHz bandwidth for the first time among published VCO-based ADC. Congrats, Praveen!

 July 2013

Jaewon Nam will present a new asynchronous SAR ADC architecture with passive gain stage at CICC Sep, 2013, achieving the best Figure-of-Merit (J/conv-step) in its class (up to date) . Congrats, Jaewon!

 Feb 2014

Cheng-Ru Ho will present the first digital PLL architecture with adaptive spur cancellation technique and low-cost time-to-digital conversion at RFIC 2014. It achieves unprecedented spur rejection by >40dB (measured data). Congrats, Cheng Ru!
