A CG amplifier when fed with a signal source having Rsig = 200 ohms is found to have an overall voltage gain of 10V/V. When a 200 ohm resistance is added in series with the signal generator the overall voltage gain decreased to 8V/V. What must gm of the MOSFET be? If the MOSFET is biased at ID = 0.2mA, at what overdrive voltage must it be operating?
