Show that two MOS transistors connected in series with channel lengths of L₁and L₂and identical channel widths of W can be modeled as one equivalent MOS transistor whose width is W and whose length is L₁+ L₂, as shown in Fig. 2.77.Assume the transistors are identical except for their channel lengths. Ignore the body effect and channel-length modulation.
