摘要：
A number of authors have proposed the use of additional operational amplifiers (op amp) for compensating the detrimental effects of the frequency-dependent gains of the op amps already used in the circuit. This technique is known as active compensation. Among all such actively compensated circuits, two such circuits have been derived from the single amplifier biquad (SAB) of Deliyannis-Friend. These two circuits possess very low passive and active sensitivities. The purpose of this paper is to compare their performances not only with respect to the active sensitivities but also from the point of requiring matched op amps and their stability. © 1990 IEEE
