Integrated circuits

We design a broad gamut of RF/microwave, analog, mixed-signal, and digital integrated circuits in silicon (CMOS) technology as well as with III-V semiconductor technology, organic materials, and emerging nanoscale materials such as semiconductor nanowires. Our design portfolio includes a host of frequency reference circuits—e.g., self-sustained ring, LC, and wave oscillators, mode-locked (soliton) oscillators, integer/fractional-N phase-locked loop (PLL) frequency synthesizers, and delay-locked-loop (DLL) timing references—, time-domain temperature sensors for microprocessor thermal profiling, analog-to-digital converters (ADCs) with various digital background calibration techniques, and a variety of application-specific integrated circuits—e.g.micro electromagnet circuits to manipulate biological cells, RF NMR relaxometry chips to detect cancer marker proteins and human cancer cells and to analyze complex hydrocarbons for petrochemical analysis, RF NMR spectrometer chips to interrogate atomic networks of complex molecules, CMOS ion-sensitive field effect transistor (ISFET) array for all-electrical DNA array technology, and a CMOS chip that operates an interface between a neuronal network and an array of vertical conducting nanowires.
