Sketch the output waveforms for the circuits (a) and (b) when a voltage waveform Vs (Figure 1) is applied at the input. Assume that the transistor threshold voltages are 0.8 V and −0.8 V for the NMOS and PMOS transistors respectively, and the time constants are much smaller than the pulse widths. For (b) show both V1 and V2. (In your answer, show both input and output waveforms synchronized) Figure 1.
