Pre-Lab B: 1. MOS transistor small-signal resistance (a) For the MOS transistor circuit shown in Fig. PL3.1(a) below, calculate and tabulate (using the Results Sheet for Preliminary Exercises) the values of the small-signal resistance Ruos from drain to source for values of control voltage Veranging from IV to 10V, in steps of 1V. Then, plot your values of Rxos versus Vc on a graph. Again, assume the MOS device parameters given at the beginning of this pre-lab. CD 1007UB V-3V Figure PL 3.1) 2. Gain-Controllable Amplifier (6) For the inverting amplifier circuit shown in Fig. PL3.1(b) (which uses an op amp defined by ‘LM741' and an MOS transistor with parameters as in the beginning of (c) this pre-lab defined by CD4007'), calculate and tabulate (using the Results Sheet for Preliminary Exercises) the gain V./V of this amplifier for values of control voltageVc ranging from OV to 10V, in steps of 1V. Then, plot the gain versus Vc on a graph. (Hint: Be careful when determining gain at V=0V.] Assume for this pre-lab that the MOS transistors have zero leakage currents.

CD4007UB VBR-3V 10002 VMw R LM741/NS Figure PL 3.1(b) (d) Hand-calculate and tabulate (using the Results Sheet for Preliminary Exercises) the 3dB bandwidth of the amplifier for values of Veranging from 4V to 10V. in steps of 1V. (e) Use SPICE to generate Bode plots for this amplifier, for values of V ranging from 1V to 10V. (Plot all curves on the same graph.) What might explain the differences inbandwidth between the hand-calculation and the simulation?
