Study of variability issues on CMOS inverter

摘要

This paper studies the impact of performance and variability effects on CMOS inverter circuits. Device mismatches, the small random variations in the characteristics of identically designed devices, occur during the manufacturing of integrated circuits. These mismatches result in behavioral variations of analog and digital integrated circuits. The impact of these random parameter variations on circuit behavior can be studied with Monte Carlo simulation by analyzing a large set of circuit instantiations with randomly varied devices and process parameters.
