Abstract

A high Q, insensitive, active RC network, usable up to several megacycles, is described. It has similar properties to the circuit proposed by Tarmy and Ghausi, but uses operational amplifiers with single-ended output terminals. The circuit can be realised with only two amplifiers; using three, the two capacitors required can be earthed.
