Question

Calculate the overall voltage gain of a Common Source amplifier fed with a voltage source having a 500k internal resistance and connected to a 5k load. The MOSFET has a gm = 6 mA/V and ro = 1M ohm, and a drain resistance rd = 20k is utilized. Then calculate the voltage gain (Av), the current gain (Ai), the power gain (Ap), and the overall voltage gain (Gv) if a common gate configuration is used to connect the above-mentioned source and load.

Step 1

We can use the following formula: Av = -gm * rd where gm is the transconductance of the MOSFET and rd is the drain resistance. Av = -6 mA/V * 20kΩ = -120 Note that the negative sign indicates that the output signal is inverted with respect to the input signal. Show more…
