The active compensation of operational amplifeir is that it compensates the phase shift and the attennation of gain of OP Amp, according as the frequency increases. The compensation circuit is applied to VCVS and interting integrator. For VCVS, the phase shift of proposed compensated circuit is not concern with the frequency and the gain chracteristic is better than the proposde circuit by Soliman, according as the rate of feedback resistors of compensated circuit changes. Voltage follower accomplishies compgnsation using the same circuit. Also, the compensation circuit to increase O-ffactor in inverting integrator is proposed.
