Introduction to Circuit Simulation Using SPICE--CMOS Inverter

Introduction:

SPICE (Simulation Program with Integrated Circuit Emphasis) is a very powerful and
one of the most widely used simulator for electrical and electronic circuits at transistorlevel
(circuit-level in VLSI terms), especially for analogue and mixed-signal circuits.

This experiment aims at introducing you to some of the capabilities of the spice program
applied to CMOS VLSI circuit design. It can perform nonlinear dc, nonlinear transient,
linear ac analysis and other type of simulations. The circuit may contain resistances,
capacitors, inductors, mutual inductors, independent voltage and current sources, four
types of dependent sources, transmission lines, and four most common semiconductor
devices: diodes, BJTs, JFETs and MOSFETs. This experiment will use SPICE’s dc and
transient analysis capabilities to analyze circuits based on CMOS n-type and p-type
enhancement mode MOSFETs and illustrate the importance of such a simulator in VLSI
Design.
