Operational Amplifier Circuit Stability

Operational Amplifier Circuit Stability: Loop Gain and Loop Phase Shift – Consider the inverting amplifier circuit and waveforms in Fig. 15-­1(a). The signal voltage voltage (vs) is amplified by a factor R2/R1, and phase shifted through -180°. The Operational Amplifier Circuit Stability is redrawn in Fig. 15­-1(b) to illustrate the fact that the output voltage […]
