Active compensation for high-frequency effects in op-amp circuits with applications to active RC filters

The use of "active compensation" in precision electronic circuits employing modern op amps, whereby the op amps in a circuit provide "self-compensating" effects to mitigate their finite bandwidth limitations is discussed. In particular, several rather subtle applications in the field of active filters are presented. A number of novel integrator circuits having high performance are presented, and experimental results which support the theoretical derivations are given. Using these integrators considerably extends the useful frequency range of the "leap-frog" and "coupled-biquad" active filters, at no extra cost.
