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 ...

Using Delta-Sigma Can Be As Easy As ADC (Part 4)

Based on the amount of e-mail I received after Part 3 of this series (Nov. 7, 2008, p. 18; www.electronicdesign.com, ED Online 19948), many of you have already guessed that an incremental integrator ...
