Question 1: 7.33 +15V 1O MO R-200k 16n 7k MO 7.33 Figure P7.33 shows a discrete-circuit amplifier. The input signal is coupled to the gate through a very large capacitor (shown as infinite). The transistor source is connected to ground at signal frequencies via a very large capacitor (shown as infinite). The output voltage signal that develops at the drain is coupled to a load resistance via a very large capacitor (shown as infinite). All capacitors behave as short circuits...

a) For the common source amplifier below, calculate the small signal gain Av -Vo Vi (from the transistor gate to the output node), the input resistance Rin, the output resistance Rout, and the overall voltage gain Gy Vo Vs (from the voltage source to the output node). Assume that the capacitors act as AC shorts and that the transistor's To is infinite (can be neglected) Note, you can use the small signal parameters that you...
