A 100MHz–2GHz 12.5x sub-Nyquist rate receiver in 90nm CMOS

Abstract

A fully-integrated, high-speed, wideband receiver called the random modulation pre-integrator is realized in IBM 90nm digital CMOS. It achieves an effective instantaneous bandwidth of 2GHz, with >54dB dynamic range. Most notably, the aggregate digitization rate is ƒ_s =320MSPS, 12.5× below the Nyquist rate. Signal recovery can be accomplished for any signal with a concise representation. The system is validated using radar-pulses and tones as the input and recovering the time-domain waveforms.
