Analytical Formulas of Output Waveform and Short-Circuit Power Dissipation for Static CMOS Gates Driving a CBC π Load

摘要

As MOSFET sizes and wire widths become very small in resent years, influence of resistive component of inter- connects on the estimation of propagation delay and power dis- sipation can no longer be neglected. In this paper we present formulas of output waveform at driving point and short-circuit power dissipation for static CMOS logic gates driving a CBC π load. By representing the short-circuit current and the current flowing in the resistance of a CBC π load by piece-wise linear functions, a closed-form formula is derived.
