摘要

The switching behaviour and the operating region of a complementary metal-oxide-semiconductor (CMOS) gate driving a resistance-inductance-capacitance (RLC) transmission line is investigated in this paper. Closed form expressions for the time the transistors operate in the saturation and triode region respectively are proposed. Closed form expressions show predictions within 10% of HSPICE results for a wide range of line and buffer parameters, making them suitable to be applied to the problem of buffer sizing, repeater insertion, short circuit power estimation and generally whenever the accurate knowledge of the operation of CMOS buffers driving a transmission line is required. In the paper useful hints for choosing the most appropriate model for the triode region of the transistors of the inductive-line driver are also given.
