transistor with its Tequivalent circuit, assuming A =0. Derive
expressions for the voltage gains v,lv, and v,/v,.

*7.33 Figure P7.33 shows a discrete-circuit amplifier. The
input signal vsig 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 for signals and as open circuits for dc.
