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 ...
To obtain the transfer function of an analog-to-digital converter (ADC), it’s intuitive to feed a ramp signal and observe the ADC output code. But the greater the resolution and precision of the ADC, ...
