Q.4 (Total: 25 marks] The schematic diagram of a CMOS inverter is shown below. The transistors can be taken to have negligible channel length modulation and both have the same magnitude threshold voltage. The mobility of electrons is twice that of holes for this technology. The inverter is designed such that Volv,=vop/2 = Yop. VOD ;/2 VDD el Vi e V (a) Sketch the transfer characteristic of the inverter and identify the oper- ating regions of the inverter in terms of the conduction state of each transistor (OFF, pre-saturation or saturated). [10 marks] (b) Establish the relationship needed between the channel dimensions of the two transistors in order for the inverter to operate such thatVolv,=Vpp/2 Vpp if the lengths of both gates are the same. Verify your assumptions. [10 marks] (c) If the length of both gates is L = 2 um, calculate the area occupied by the transistor gate. (5 marks]
