Figure P7.33 shows a discrete-circuit amplifier. The input signal "g 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 de. (a) If the transistor has V, IV, and A, = 4 mA', verify that the bias circuit 1.5 V,1, 0.5 mA, establishes Vs = .V, a and V, = +7.0V. That is, assume these values, and verify that they are consistent with the values of the circuit components and the device parameters (b) Find 3, and r, if V, = 100 v. MOS (C) Draw a complete small -signal equivalent circuit for the transistor with V, IV. amplifierassuming all capacitors behave as short circuits , and the gain at signal frequencies.
