A pulse-width modulator (PWM) is a common way of generating analog outputs from a digital component. A PWM replaces a digital-to-analog converter (DAC) that generates analog voltage or current ...
Simply adding a diode and potentiometer to a 555 timer operating in the asynchronous mode yields a pulsewidth modulator (PWM) with a duty factor adjustable from 1% to 99% (Fig. 1). Applications would ...
Although the Altera MAX IIZ CPLD is a digital programmable logic device, it is versatile enough to control analog systems. This article shows how MAX IIZ CPLDs – alone or with a few passive ...
