A Broadband CMOS Multiplier-Based Correlator for IR-UWB Transceiver SoC

A multiplier-based correlator is an important component for impulse radio ultra-wideband (IR-UWB) receiver. Classified as correlation-type demodulator, this type of correlator uses correlation-type demodulation. This paper reports design and implementation of a fully integrated low-power broadband multiplier-based correlator for a 3.1-10.6 GHz full-band UWB receiver in 0.18 mum CMOS that consists of an UWB multiplier and a first-order RC integrator with a 200 MHz bandwidth Measurement results confirm the correlation-type demodulation function and achieve a conversion gain of 0 dB, noise figure of 8.2 dB and power consumption 52 mW for the UWB multiplier.
