Suppose, as seen in Fig. 19.78, that instead of using a half-replica of the delay cell in Fig. 19.58, the full delay cell is used to generate V
_{r b l a s}. electrically is there any difference in V
_{r b l a s}
when comparing the full- and half-replica circuits? What may be the benefit of using a full-replica of the delay cell?
