Common gate output impedance

WebApr 5, 2024 · In the Common Drain configuration (similar to common collector), the input is applied to the Gate and its output is taken from the Source. The common drain or “source follower” configuration has the highest input impedance and low output impedance. The voltage gain is unity, although the current gain is high. The input and output signals ... WebMar 13, 2012 · The output stage is an FET common gate amplifier which is driven by the input stage. Rd is the drain resistance of the output stage. Output voltage (Vout) is taken from the drain terminal of Q2. Since the gate of Q2 is grounded, FET Q2’s source voltage and the FET Q1’s drain voltage are held almost constant.
