Abstract

A technique is presented for automatically tuning integrated-circuit active RC filters. The control circuit uses a combination of digital and switched-capacitor techniques and is suitable for implementation in MOS technology. Simulated performance for an 80kHz third-order lowpass filter is given and indicates that the degradation of linearity due to the tuning technique is minimal.
