Delta-sigma modulation is a cornerstone approach for high-resolution analogue-to-digital conversion, combining oversampling with active noise shaping to achieve superior signal fidelity. In these ...

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 ...

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 ...

Audio D/A converters using sigma-delta conversion techniques are not new, so designers have learned to deal with some of the problems that are inevitable in their implementation. But now Wolfson ...

Every high-voltage electrical application in today’s world requires monitoring, whether it’s on the electrical grid and making sure that the nominal current is flowing downstream, or in a motor and ...
