NGSPICE Simulation of CMOS Circuits

Abstract: NGSPICE is a powerful open-source SPICE simulation software in command line, which can efficiently simulate CMOS circuits. Basic logic gates, including Not, Nand, And, Nor, are implemented and analyzed. The delay parameters and response plots can help understand the circuit characteristics. As examples, the 8-input NAND gate with three distinct designs is investigated, and the clock controlled SR latch is also simulated to design appropriate MOS parameters.
