Q1. (a) Design the transistor-level circuit diagram for a single static CMOS logic gate which implements the logic function: O/P=A+B+С· D where A, B, C and D are the logic gate inputs and O/P is the logic gate output. Note: You need to describe and explain the steps you have followed in your approach to design the circuit diagram (e.g., by inspection and/or by Boolean algebra manipulation). (b) Complete the following 6-input CMOS logic gate designs by including the missing pull-down or pull-up path and derive the combinational logic expression they implement: Voo DQ10 FQ12 A-Q7 B-Q8 c-Q9 E-Q11 ? ? VDD Complete the logic gate design by including the missing pull-up path O/P O/P CH[Q3 FQ6 B-CQ2 Complete the logic gate design by including the missing pull-down path DQ4 EQ5 A-Q1 Vss Vss Fig. 1 Fig. 2 Hint: Use the design rules we discussed in lecture 2 regarding static CMOS logic gates. Then, once you do come up with a solution, double check whether it is correct by ensuring that it does result in a valid static CMOS logic gate design (i.e., it follows all the design rules for static CMOS logic gates). To derive the logic expression, remember that the pull-down path maps directly to an inverting expression (a logic expression with a single inversion bar above it) where each series connection of MOSFETs results in an AND function and each parallel connection of MOSFETS results in an OR function.
