The XOR gate PD seen in Fig. 19.4 can exhibit input-dependent skew. In other words, the delay from one of the inputs changing to the output of the PD will not be precisely the same as the delay from the other input to the output. Design an XOR PD that doesn't exhibit input-dependent skew. Hint: see Fig. 18.16.
