Abstract :
The dynamic power consumption of a complementary metal-oxide-semiconductor (CMOS) gate driving a resistance-inductance-capacitance (RLC) transmission line is investigated in this paper. The closed-form solution for the dynamic power has been carried out by a simple time domain model for input impedance of a lossy transmission line, specifically developed to be used in conjunction with MOS macromodels. The proposed solution agrees with circuit simulations within 1% error for a wide range of line parameters, and it demonstrates how power dissipation localized in the wire resistance may be a significant aliquot of the global power consumption
