    20.1: Theory Overview

    Sallen and Key VCVS filters are very straightforward to implement, utilizing a single op amp to create second order high or low pass filters. The filters are based around a series-parallel non-inverting amplifier. In the equal component variation, the damping or alignment of the filter is set by the amplifier’s pass band voltage gain. The corner frequency of the filter is set by the tuning resistors and capacitors.
