Plot the input/output characteristic of the XOR PD for two cases. To receive full credit, you must show the minimum and maximum values on the graphs. Note that Xout is the average output of the PD. (a) The circuit has a single-ended output that swings between 0 and VDD. (b) The circuit has a differential output that swings between −V0 and +V0. Use a graph similar to the one depicted below for both parts.
