Abstract

In this paper, we designed 3.3-V receiver/transmitter transconductance-C (Gm-C) filters for baseband analog front-end of wireless transceiver applications. The receiver filter consists of the 6^th-order Gm-C filter including the 2^nd-order group delay equalization. The filter on the transmitter path consists of the 5^th-order Gm-C filter. Both filters are equipped with relevant input/output buffers and on-chip frequency tuning circuit. The filters are fabricated and verified through measurements in a 0.18-μm CMOS technology.
