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/sup th/-order Gm-C filter including the 2/sup nd/-order group delay equalization. The filter on the transmitter path consists of the 5/sup 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-/spl mu/m CMOS technology.
