## EE 42/100. Introduction to Digital Electronics

### Description

Catalog Description: Electronic circuit elements, theory, digital circuits applications. Digital signals, logic gates, switching. Kirchoff's laws, nodal analysis. Graphical methods for nonlinear circuits. Thévenin, Norton equivalents, transients. Dependent source, amplifiers. Operational amplifiers and comparators. MOS transistors as switches, MOS I-V models for logic circuit analysis. Transfer curves. Symmetry of PMOS and NMOS devices and CMOS circuits. Resistance and capacitance models for stage delay.

Course objectives: EE 42/100 (and EE 43) serve as an introduction to the principles of Electrical Engineering, using electronic devices to communicate, solve problems, and manipulate our environment. EE 42/100 will start with basic concepts about charges and currents, develop devices such as circuits to translate design concepts into reality, and study some high level applications including logic circuits, amplifiers, power supplies, and communication links.
