Pass Gate Pass gate logic circuit are shown in the figure below. Transistors are sized on the figure (in red font) for all the paths (output to input, output to GND) to have equivalent resistance to equal Ru (unit resistance of minimum-sized NMOS). Table shows the input combinations (in logical values), and you will be asked to determine the actual voltages at the output. Note that supply voltage is Vdd, and threshold voltage of a transistor is Vth (for both PMOS and NMOS). Answer the Questions 10, 11, 12, 13, 14, 15 below.         If you show your work and answers on work paper, partial credit could be awarded to the correct work even with incorrect answer.
