A common-gate amplifier using a n-channel MOSFET for which gm = 5mA/V has a 5k drain resistance and a 2k2 load resistance. The amplifier is driven by a voltage source having a 200 ohms resistance. What is the input resistance of the amplifier? What is the overall voltage gain Gv? If the circuit allows a bias current increase by a factor of 4 while maintaining linear operation, what do the input resistance and voltage gain become?
