Abstract:In this paper, an optimum stage ratio (tapering factor) for a tapered CMOS inverter chain is derived to minimize the product of power dissipation and jitter variance due to device mismatch. Analysis shows that this optimum stage ratio (2.4) is lower than that of minimum delay (3.6) and minimum power-delay (6.35) product. This analysis is verified by simulation results using standard 180 nm as well as 90 nm CMOS technology. Knowledge of the optimum stage ratio helps to design low power low mismatch jitter buffers for multi phase clock generation circuits that can drive large load capacitances.
