  • Abstract
    A low-IF polyphase channel filter for a dual-mode Bluetooth/Zigbee transceiver is described. Implemented in a standard 0.18-μm 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.
