The distortion performance of an amplifier is determined not only by open loop linearity, but also the negative feedback factor applied when the loop is closed. In most practical circumstances ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

From earlier work in this series, distortion from the small-signal stages may be kept to levels that will prove negligible compared with distortion from a closed-loop output stage. Similarly, future ...
