Op Amp Circuit Bandwidth and Slew Rate Test

Op Amp Circuit Bandwidth and Slew Rate Test: Low Cutoff Frequency – Op Amp Circuit Bandwidth and Slew Rate Test are direct-coupled internally, so where they are employed in direct-coupled applications, the circuit lower cutoff frequency (f1) is zero. In capacitor-coupled circuits, the lower cutoff frequency is determined by the selection of coupling capacitors. The […]

Frequency Compensation Methods

Frequency Compensation Methods: Phase-Lag and Phase-Lead Compensation – Lag compensation and lead compensation are two Frequency Compensation Methods often employed to stabilize op-amp circuits. The phase-lag network in Fig. 15-7(a) introduces additional phase lag at some low frequency where the op-amp phase shift is still so small that additional phase lag has no effect. It […]
