Closed loop unity gain

WebPhase margin and its important companion concept, gain margin, are measures of stability in closed-loop, dynamic-control systems. Phase margin indicates relative stability, the tendency to oscillate during its damped response to an input change such as a step function. WebThe input (V in) and the output (V out) have the following relationship. This relationship is called a closed-loop gain (represented as G CL in dB scale and A CL in linear scale). …
