ECE 188: Computer Interface Circuits Catalog description: 3.0 units The use of computer simulation in circuit analysis and design is emphasized. Pulse and digital wave shaping circuits for integrated circuit families (TTL, CMOS, ECL, TTL). Power supplies as applied to both large- and small-scale systems; power and ground buss structures. Line drivers and receivers; single-ended versus differentially driven lines. Prerequisites: ECE 085, ECE 145 Course objectives: For students to 1.
