About Me

I'm an integrated circuit (IC) design engineer, with a focus in analog and mixed-signal circuit design for sensors. My doctoral research focused on the design of CMOS transducers and programmable inteface circuits (AFE, ADC, etc.) for resource-efficient sensors. Some of the target applications I have explored are in the high-energy physics, environmental, and biomedical domains. I did my PhD work in Dr. Matthew Johnston's Sensors and Integrated Microelectronics Laboratory (SIM Lab) at Oregon State University.

A key challenge in making a successful sensor system is to extract physical information (vibration, flow rate, radioactivity, etc.) from the electrical signals provided by a transducer as efficiently (low power, small area) as possible without sacrificing too much performance (noise, resolution, speed, linearity). This involves exploring various interesting trade-offs in the design of the analog/mixed-signal interface circuits. In addition, one often needs a good understanding of the application which makes the work somewhat inter-disciplinary. While it's challenging, I find this design process to be extremely rewarding.
