Sigma-delta modulation improves resolution in programmable interrupt controller analog outputs

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

Sigma-delta techniques extend DAC resolution

Motion control systems often require digital-to-analog converters with high resolution but not high accuracy. Because high-accuracy DACs are expensive and consume valuable board space, a good solution ...
