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 ...
The inverters in a CMOS CD4069 can be used for both analog as well as digital applications. This Design Idea illustrates this by using all six inverters in a 4069 package to make a closed loop, ...
