2. Consider the design of a CMOS compound OR-AND-INVERT (OAI21) gate computing Y = overline{(A + B) . C}. a) Sketch a transistor-level schematic. Verify its operation by truth table. (5+5 points) b) Sketch a stick diagram of the OAI21 gate of part a). Estimate the area from the stick diagram. If you were using 130 nm CMOS technology, what will be the cell area? (7+5+3 points)

Step 1
** The OAI21 gate computes the function Y = (A + B) · C. This means the output Y is high when either A or B is high and C is also high. It is an OR-AND-INVERT gate, meaning it first ORs A and B, then ANDs the result with C, and finally inverts the output. **Step Show more…
