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 ...

Sawtooth- or exponential-ramp relaxation oscillators are common and generally easy to build. However sometimes a cleaner waveform is desired, and generators of even-symmetric waveforms are a bit more ...

Using standard circuits and no auxiliary voltage generators (such as charge pumps or inductive dc-dc converters), it's difficult to build a precision, rail-to-rail ramp generator that operates on a ...

Function generators (FGs) are measurement instruments in the category of waveform sources. They grew out of both a need for a versatile source of multiple waveshapes and from some interesting analog ...
