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. (a) If the transistor has Vt = 1 V, and kn = 4 mA/V2 , verify that the bias circuit establishes VGS = 1.5 V, ID = 0.5 mA, and VD = +7.0 V. 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 VA = 100 V. (c) Draw a complete small-signal equivalent circuit for the amplifier, assuming all capacitors behave as short circuits at signal frequencies. (d) Find Rin, vgs/vsig, vo/vgs, and vo/vsig.

You are tasked with designing the capacitively coupled MOSFET amplifier circuit in Figure 4. The internal capacitances of the MOSFET are negligible. Assume that the frequency of the input signal is sufficiently large such that; the coupling capacitors behave as short circuits to the signal component. The MOSFET has threshold voltage Vt = 1 V and transconductance parameter kn = 2 A/V2. i) If the DC voltage at the drain is required to be 5 V. Determine the range of DC voltages at the gate, that will keep the MOSFET in saturation mode? ii) Determine suitable values for RG1, RG2 and RD in order to keep the DC voltage of the gate at 3.5 V. You may use the following equation for the drain current of a MOSFET in saturation region. iD = kn/2(vGS - Vt)2 iii) Determine the range of input signal voltages vi, that could keep the MOSFET in saturation region for the values of RG1,RG2 and RD determined in question 2) b) ii).
