WebJFET Common-Source (CS) Fixed-Bias Configuration • The input is on the gate and the output is on the drain. • Fixed bias configuration includes the coupling capacitors c1 and c2 that isolate the dc biasing arrangements from the applied signal and load. • They act as short circuit equivalents for the ac analysis. AC Equivalent Circuit WebDC Bias Bias establishes the DC operating point (Q-point) for proper linear operation of an amplifier. If an amplifier is not biased with correct DC voltages on the input and output, it can go into saturation or cutoff when an input signal is applied. Figure 1: Examples of linear and nonlinear operation of an inverting amplifier
