Active Sallen-Key RC-High-Frequency filter based on non-inverting voltage followers

A new high-pass filter (HPF) circuit of the second-order Sallen-Key family has been developed and studied, in which independent adjustment of the main parameters is realized -the pole frequency, the quality factor of the pole and the transmission coefficient. The basic equations for the transfer functions and HPF parameters are presented. The results of computer simulation a proposed circuits HPF in CAD Micro-Cap 12 are shown.
