A transistor schematic diagram of a digital circuit is shown below (Fig. 2.1), with the MOSFET parameters µCox(W/L) = 100 µA/V2 and |VT| = 0.7 V. The supply voltage VDD is 3.0 V. Fig. 2.1 (a). What logic gate is it shown in Fig. 2.1? Draw the logic gate symbol of the above digital circuit. (b). What are the operation modes of the MOSFET M1 for the input voltage Vin = 0 V, 2.0 V and 3.0 V ? (c). Sketch a graph showing the static voltage transfer characteristics (VTC) (i.e. Vout versus Vin ) of the logic circuit (Fig. 2.1). Any turning point(s) or important features (e.g. voltage levels) as well as axes must be shown clearly or labelled explicitly. On the same graph, sketch a second curve if RL = 100 kΩ and a third curve if RL = 4 kΩ. (d). Now, instead of using a load resistor, a depletion-mode MOSFET of the same type is used for implementing the logic gate in addition to the originally given MOSFET. Draw a schematic circuit diagram of such an implementation using two MOSFETs.

Assume that the MOSFET has the following parameters: Vt = 1 V, K = 0.4 mA/V2 VA = 40 V. It is connected as an amplifier as shown in Figure Q4 and vs is an AC input voltage and vo is the AC output voltage. The DC drain voltage VD is set to be 0 V. Further assume that all the capacitors in the circuit are very large. Figure Q7. (a) Which type of amplifier configuration does the above circuit (3 marks) belong to? What are the electrical properties of this type of amplifier configuration? (b) Show that the MOS transistor operates in the saturation mode. (3 marks) State one electrical characteristic of a saturated MOS transistor. (c) Determine the drain current ID. (10 marks) (d) Design the load resistance RL such that the AC voltage gain vo/vs of (10 marks) the MOSFET amplifier equals -10 . (e) Suppose the amplitude of AC input vs is 0.2 V and the AC voltage (4 marks) gain of the amplifier equals -10. Do we have a distorted AC output waveform?
