Consider the amplifier shown in Figure 1. The MOSFET operates in its saturation region and is characterized by the parameters VT and K. The input voltage vI comprises the sum of a DC bias voltage VI and a sinusoid of the form vi = Asinωt. Assume that A is very small compared to VI. Let the output voltage vO comprise a DC bias term VO and a small-signal response term vo. a) Determine the output operating point voltage VO for the input bias of VI. b) Determine the small signal gain of the amplifier. c) Draw the form of the input and output voltages as a function of time, clearly showing the DC and time-varying small-signal components.

Consider the amplifier shown below along with a description of its voltage gain in the s-domain (Av(s)) a) Determine expressions for the poles and zeros, if any. Show your work! You may leave your answers as a function of Rb instead of R1||R2. b) Crudely graph a straight line approximation for the Bode Plot of |Vo/Vin| as a function of frequency. If there are multiple poles you may assume that the one at the output (containing terms at the output: RL, Rd, C2 ) is larger. Av(s) = -gm Rb/Rb + 1/sC1 (Rd||(1/sC2 + RL)) Where: Rb = R1||R2 and the notation Z1(s)||Z2(s) denotes that impedances Z1 and Z2 are in parallel

A transistor schematic diagram of a digital circuit is shown below (Fig. 3.1). The sizes of the MOS transistors are given as ratio (W/L)n = 4 and (W/L)p = 2. |It is also given that |VTn| = VTp = 0.5 V and µnCox = 10-4 A/V2 while µpCox = 5 × 10-5 A/V2 . Fig. 3.1 (a). Draw the logic gate symbol of the above CMOS digital circuit. (2 marks) (b). Sketch the output waveform Vout for the given input voltage signals VA and VB. Assume that the logic circuit is fast enough to respond to the given input waveform. Voltage levels and any other key features must be labelled properly. (8 marks) (c). If both the inputs VA and VB are connected to VDD, determine the equivalent resistance linking the output to ground. (7 marks) (e). If the inputs VA and VB are tied together, sketch a graph of the output voltage Vout as a function of VA from 0 V to 1.8 V in the static case. Any turning point(s) or important features (e.g. voltage levels) as well as axes must be shown clearly or labelled explicitly. (8 marks)
