Q1. A) Sketch a static CMOS gate computing the following equation. You may assume you have both true and complementary versions of the inputs available. Y = (B⋅(A+C)+D)⋅(A+D)¯ B) Design the size of transistors in a way that tpdr = tpdf . Explain the different steps that you took to reach the final answer. Wmin = 200 nm L = 60 nm μn = 2μp VDD = 1.0 V C) First, convert the circuit to its RC model. Then, estimate tpd of the designed circuit using the Elmore delay model. Suppose that a unit transistor has R = 10 k and C = 0.1 fF and your circuit is deriving a 20 FF capacitance (a 20 fF capacitor is connected to the output).
