Abstract :
An analog correlator for ultra-wideband (UWB) vehicular short-range radars (V-SRR) is presented. The correlator is designed for operation at 22-29GHz using the IBM 90nm RFCMOS process. The correlator consists of a multiplier, a Gm-C integrator, and a post amplifier. A novel four-quadrant transconductance multiplier (FQTM) is proposed to achieve high gain, and a Gm-C integrator is designed to improve the holding time of the correlator. Simulations show that the proposed FQTM has 9.54dB gain increase, and the correlator achieves 2.3ns of holding time and uses 15 mW of power.
