Research in the area of electronic devices includes the design of gallium arsenide RF, and microwave integrated circuits. Among the circuits that have been designed for industry, is a dual conversion TV turner chip used in cable TV boxes, fiber optic receivers, log amps, cell phone receivers, DBS receivers, and a high speed front end for a silicon CMOS PLL. Research is also conducted in the areas of opto-electronics devices, VLSI design, analog phenomena in digital circuits, analog and digital circuit design, CAD for VLSI, and VLSI testing.
