I maintain a broad interest in solving problems in image processing, speech communication, and analog decoding using low power analog Very-Large-Scale-Integrated (VLSI) circuits.  I have successfully developed a detailed linear filter bank model for processing acoustic signals in real time.   The filters employ MOS transistors operating in the subthreshold region for minimum power consumption and maximum tuning range.  These models served as front-ends for noise-tolerant automatic sound recognition systems.  I have also investigated the use of two-dimensional analog “resistive” grids for solving Poisson’s equation.  Many applications in adaptive optics require the solution of Poisson’s equation at bandwidths much higher than digital processors can provide.  By contrast, analog VLSI “resistive” grids naturally yield solutions at high bandwidths, consuming far less power, area, and weight than the digital counterpart.  Finally, I am looking at analog signal processing circuits as a means to develop high-speed analog error-correcting decoders.
