摘要：

A flexible multimode receiver architecture for software defined radio systems with focus on GSM, WCDMA and CDMA systems has been designed in a 120 nm CMOS technology. The receiver consists of a wideband coilless common gate LNA2 with gain switches and a high linearity down-converter with current interface between mixer and baseband-filter. The LO signal of a 8 GHz VCO and divider with ratio 4 respectively 8 covers the whole receiver frequency range. The receiver consumes 32 mA at 1.5 V supply voltage.
