Simulação SPICE de circuitos CMOS

Abstract

In this work, we analyze models available in the simulation program SPICE ( textit Simulated Program with Integrated Circuits Emphasis) for transistor technology CMOS ( textit Complementary metal-oxide-semiconductor). Such devices are prodominantes component in electronic circuits, due to the CMOS technology is the most widely used in the manufacture of integrated circuits. Because of the importance of these devices and the large number of applications, CMOS transistors are devices with as many different models available in SPICE language. Some of these models are analyzed and compared here, namely: level 1 model MOSFET, MOSFET model level 2 and MOSFET model level 3. Also, are simulated two applications: a CMOS amplifier and a CMOS inverter.
