## Abstract

In this chapter, we consider circuits that involve non-linear operation of the operational amplifier. These can be used to realize waveform generators which are circuits that produce a variety of non-sinusoidal waveforms. They are fundamentally instrumentation building blocks used for signal generation and test and measurement. Typically, waveform generators produce square waves, triangular waves, pulses and in some cases arbitrary waveforms over a range of frequencies with constant amplitude. Here we discuss comparators, op-amp-based free-running (astable) and one-shot (monostable) multivibrator circuits as well as precision rectifiers and other non-linear circuits. At the end of the chapter, the student will be able to:
