Distortion Generation with Source Resistance and Nonlinear Beta
For a basic MOS stage, whether’ single-ended’ or differential, the input resistance at low frequencies is extremely large because of the insulated-gate structure of the device. Therefore, the presence of a finite resistance of a signal source has no effect on the performance of the stage. Only at very high frequencies is there an interaction between the signal source and the input capacitance.
