EE 435 Lab 5 Spring 2009 Two Stage Op Amp Design 1 Introduction In many applications of operational amplifiers, the gain of a single-stage amplifier is not adequate. Operational amplifier architectures that use two or more gain stages are widely used when higher gains are needed. Additional phase shift is invariably introduced when multiple gain stages are cascaded and compensation of these structures is invariably required to maintain acceptable magnitude response or time- domain response of feedback circuits that use the multiple-stage architectures. Of the multiple-stage architectures that are used, two-stage configurations are the most popular because primarily of the challenges associated with compensating three or more stages. In this experiment, a two stage op amp using the basic architecture shown in Fig. 1 will be designed. After the initial two-stage design is completed, the right half-plane zero will be removed.
