Comments on "A module generator for optimized CMOS buffers

For the original article see ibid., vol.9, no.10, p.1028-46 (1990). In the above-titled paper A.J. Al-Khalili et al. claim that the expression derived by the commenters (1987) for the short-circuit energy dissipation per transition for a CMOS inverter while the n-channel transistor is discharging the load capacitor is not correct, and they suggest that some mistakes were made during the integration. The commenters point out that a rederivation showed that their expression is correct, and even if it is given for equal p- and n-channel transistors, it can easily be generalized to arbitrary p- and n-channel transistor sizes.<>
