For recent work please refer to my Research Group's webpage.
Below is a list of projects, circuit designs, papers, and patents I have worked on in before going back to academia. For most you can find details in related technical publications.
High Speed and RF circuits
At Celight, we designed a 5Gs/s 5bit A/D convertor in a 40GHz SiGe process. Unfortunately, we never got the chance to experimentally verify the samples. The ADC was part of a receiver for coherent optical communications (see SCEE2002).
An Injection Locking Scheme for Precision Quadrature Generation
At Broadcom, I was part of the design team for the BCM3415: CMOS TV Tuner for Cable Modem applications.
A 5.3 GHz Programmable Divider for HiPerLAN in 0.25um CMOS
A Fully Integrated VCO for 5GHz applications
A 2.4GHz CMOS VCO with MCM inductor
A 900 MHz Double Quadrature CMOS Upconvertor
Analytical Model for Planar Inductors
A 1 GHz CMOS Upconversion Mixer
Device Mismatch: Characterization & Design Implications
Impact of Device Mismatch on the Speed-Power-Accurary Tradeoff in Analog Circuits
Mismatch Charaterization of MOS transistors
(Parallel) Analog Signal Processing
An Analog Parallel Array Processor for Real-time Sensor Signal Processing
A 4x4 Cellular Neural Network Chip
Full Analog CMOS Integration of Very Large Time Constants
