A 1.9 GHz wide-band IF double conversion CMOS integrated receiver for cordless telephone applications

A number of recent efforts have concentrated on highly-integrated radio receivers using a low-cost silicon process such as CMOS. This prototype monolithic CMOS receiver combines RF and baseband functionality by taking the carrier signal at the LNA input and producing a 10 b digital baseband waveform. A wide-band intermediate frequency double conversion (WBIFDC) architecture eliminates the need for external narrow-band IF filters.
