A 0.5mum CMOS chip contains a 5th-order continuous-time filter, a low output-impedance driver, and an active rectifier. The chip boosts the selectivity of an external passive LC LPF and achieves an ADSL isolation of 70dB at 30kHz, while maintaining a passband flatness of 0.23dB. It consumes 35mW from a 5V supply and reduces the number of transformers and the size of POTS/ADSL splitters
