Question: A CG amplifier using an NMOS transistor for which 8 . = 5 mA / V has a 5 - k$ drain resistance R ,

A CG amplifier using an NMOS transistor for which8.=5 mA/V has a 5-k$ drain resistance R, and a 5-k$2 loadresistance R,. The amplifier is driven by a voltage source with a 250-2 resistance. What is the input resistance of the amplifier? What is the overall voltage gain G,? By what factor must the bias current I, of the MOSFET be changed so that R. matches R,,?
