Operational Amplifier Design

Operational Amplifier Design

Course Overview

A major component in many of today's analog electronic circuits is the operational amplifier. In practical applications, amplifiers have specifications that are, if not difficult, impossible to satisfy using basic single stage amplifiers. In most cases, more advanced amplifier topologies must be used to achieve high gain, high input impedance, and low output impedance. This course provides the trainees with adequate background and experience in the analysis and design of a two-stage CMOS amplifier. It also discusses issues involved in designing this amplifier for practical applications like the negative feedback. This will enable the trainees to design and implement their own two-stage CMOS amplifiers for real applications.

Course Prerequisites

The trainees for this course are expected to have completed the Introduction to Analog IC Design Course offered by PIIC or any equivalent course/workshop offered by any institution. The trainees are expected to have a background and experience in analysis and design of basic analog blocks i.e. single stage amplifiers, current mirrors, and differential amplifiers including their biasing, small signal analysis, and frequency response. A background on linear systems analysis e.g. Laplace transforms, bode plots is also required. The trainees are also expected to have experience in schematic entry and circuit simulations using Cadence Virtuoso or Synopsys Custom Designer.
