Adjust the CMOS inverter to either reduced leakage or decrease delay by following ways,
Reducing Leakage Current
Utilize a larger PMOS (p-channel metal-oxide-semiconductor) transistor and a smaller NMOS (n-channel metal-oxide-semiconductor) transistor. This helps minimize the sub-threshold leakage current, as PMOS transistors generally exhibit lower leakage compared to NMOS transistors.
Decreasing Delay
Reduce the sizes of both the PMOS and NMOS transistors to decrease the channel resistance and improve the switching speed. This can be achieved by adjusting the width-to-length ratio of the transistors. Utilize high-performance CMOS processes that offer faster transistor switching speeds and reduced parasitic capacitance.
