IEEE Circuits and Systems Society Tour of South America, 1998 FUNDAMENTALS OF ANALOG INTEGRATED CIRCUITS Lecturer: Dr. Edgar Sanchez-Sinencio This course deals with basic building blocks involved in analog-to- digital converters, amplifiers and filters. A simple one transistor amplifier is first discussed, and different advanced topologies dealing with more complex amplifiers with one basic driving transistor will be presented. The fundamental four types of amplifiers with either voltage or current as their input (or output) will be discussed. The need of a differential pair is presented and the topology of a conventional two stages operational amplifier Is described in detail. BASICS OF DIGITAL INTEGRATED CIRCUITS DESIGN Lecturers: Profs. Martin Shellenberg and Jose Silva Martinez The main goal of this short course is to provide a circuit and system view of Digital Integrated Circuits Design. Special attention will be paid on speed and power dissipation; it will be shown that the optimization of the design requires a careful design at several levels: technology, circuit, logic, architecture and algorithm. In this lecture, circuit, logic and some architectural examples will be covered. Outline of the course: Inverters and their properties Combinational logic (standard cells and gate arrays) Switching properties of CMOS gates Sequential logic (static, domin, NORA, etc.) Digital systems (Decoders, PLA's, Adders, ALU's, FSM) Design examples RECENT ADVANCES IN A/D AND D/A CONVERTERS Lecturer: Prof. Franco Maloberti A/D and D/A converters are becoming key elements for the implementation of future generation applied specific integrated systems (ASIS). They will include all the processing chains, starting from the analog representation of the input up to the power control to drive the actuators. Here we discuss the existing problems and we present some recent advances in the area of data converters with a special emphasis on CMOS implementations. Outline of the course: Introduction and state of the art Practical limits to data conversion Video converters Sigma delta converters Non conventional use of sigma delta Low voltage low power data converters PRINCIPLES OF ANALOG SIGNAL PROCESSING Lecturer: Dr. Jose Silva-Martinez In the design of mixed -mode integrated circuits and systems, the use of high-performance analog building blocks is unavoidable. Some of the most important analog circuits are low-noise preamplifiers, high-performance filters, analog-digital converters and power amplifiers.
