Integrating vs. TIA front ends for compressive-scan cameras

A shootout between the two major classes of transimpedance amplifier (TIA) designs for one difficult corner of the design space.

13.5 nm EUV Lithography: Tin Droplet Detection System

When you're hitting a droplet with enough pulsed CO2 light to generate X-rays efficiently, you have to know exactly when it's going to cross the focus.

RF Design for Ion Trap Mass Spectrometer RGA

Producing an integrated model of circuit conditions and ion motion, allowing optimization of circuit and excitation parameters, plus sanity checking

Touch Panel Displays: Low-Cost Optical Front End

In cooperation with Flatfrog Laboratories AB, Lund, Sweden. This one was interesting mostly due to the requirement for high and stable performance at an absolute rock-bottom cost.

Plasmonic Nano-Antennas for Thermal Infrared Pixels

This was a seedling design study for a DARPA program that never got funded. It leveraged POEMS and my antenna-coupled tunnel junction devices, adding a couple of novel wrinkles: metal-insulator-metal varactors and parametric readout using a 10 GHz pump frequency. Hopefully there will be a chance to revisit this, because it was potentially a pretty sweet solution.
