It’s not always easy to design a ramp generator whose ramping frequency can be changed without manipulation of capacitors or inductors. Many ramp circuit designs are available, but they may not be ...
Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...
This application note outlines the implementation of a single-supply, triangular wave oscillator using the MAX9000 and some passive components. The application circuit uses an op amp, comparator, and ...
