Using De Morgan equivalent gates and bubble pushing methods to redraw the circuit in Figure 2.83 so that you can build the equivalent logic within a single stage of static CMOS gate.

(a) Write down the equivalent Boolean equation after bubble pushing.

(b) Sketch a transistor-level circuit for the Boolean equation. Use a minimum number of transistors.

Hint: Pushing bubbles towards the output will make it have a negated output
