Unformatted text preview: capacitor (shown as infinite). (a) If the transistor has V t = 1V and k n ’W/L = 2mA/V 2 , verify that the bias circuit establishes V GS = 2V, I D = 1mA, and V D = 7.5V. That is, assume these values, and verify that they are consistent with the values of the circuit components and the device parameters. (b) Find gm and ro if V A = 100V (c) Draw a complete small-signal equivalent circuit for the amplifier assuming all capacitors behave as short circuits at signal frequencies (d) Find R in , v gs /v sig , v o /v gs , and v o /v sig .
