A low-IF polyphase channel filter for a dual-mode Bluetooth/Zigbee transceiver is described. Implemented in a standard 0.18-pm CMOS process, the filter has a fifth-order 0.5-dB equiripple bandpass response and employs novel transconductor and preamplifier designs. It consumes ⩽1 mW and achieves image band rejection ⩾44, dB, input referred noise of ⩽ 52.2 µVrms and input referred third-order intermodulation intercept of ⩾20 dBVp, which gives a spurious-free dynamic range of ⩾68.4 dB. Chip area including its tuning circuit is 0.23 mm². [ABSTRACT FROM AUTHOR] |
