Abstract

A filter-based, single-sideband mixer is proposed for realization of fast switching local oscillation signal generator for MB-OFDM UWB application. This mixer utilizes switched-filtering tank as the load to provide the required sideband suppression requirement of output signals. The circuit is designed by using standard CMOS process technology. The mixer provides a sideband rejection capability more than 30 dB. The required power consumption is 17.5 mW with buffers and 7.43 mW without buffers at the supply voltage of 1.8 V. The total chip area of core circuits is 0.68×0.78 mm².
