Abstract

The simulation results of two Sallen-Key bandpass implementations with standard operational amplifiers are compared and discussed. The implementation using a voltage follower as a controlled source compares favourably with the one using equal valued passive components. Voltage-mode and current-mode Sallen-Key implementations from translinear conveyors with unity gain are described. The filters use five passive components so that the quality factor Q can be adjustable from one of them, without varying ω0. Simulation results are given and discussed.
