Abstract
The performance of a conventional op amp, having a g.sub.m stage and an integrator, is improved by placing a current mode filter between the g.sub.m stage and the integrator, which has a current gain of much less than one and is substantially without phase shift at the op amp's resonant frequency, permitting stabilization with a relatively small compensation capacitor. This improves the signal slew rate and harmonic distortion.
