An active POTS filter consisting of a small external L-C low-pass filter and a selectivity booster chip is presented. The filter achieves an ADSL attenuation of more than 70 dB at 30 kHz while maintaining a passband flatness of 0.2 dB. This active filter requires fewer transformers and is smaller than a passive filter with the same performance. The 0.5-mum CMOS booster chip contains a fifth-order continuous-time filter, a low output-impedance driver, and an active rectifier and consumes 50 mW from a 5-V AC supply
