Abstract

Elimination of the p-MOS transistor from the pass gate network significantly reduces the parasitic capacitances associated with each node in the circuit, thus, the operation speed is typically higher as compared to the CMOS counterpart. But then the improvement in the transient characteristics comes at the price of increased process complexity. In Complementary pass transistor logic (CPL) circuit, the threshold voltage of the n-MOS transistors in the pass gate network must be reduced to about the zero voltage through threshold adjustments implants in order to eliminate the threshold voltage drop. Thus on the other hand reduces the overall noise immunity and makes the transistor more susceptible to sub threshold conduction in the off mode. Presented CPL design style is highly modular as a wide range of function can be realized by using this basic pass transistor structure.
