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 ...

Incremental analog-to-digital converters (ADCs) and delta-sigma modulators represent two advanced architectures that have been pivotal in high-precision signal processing. Incremental ADCs convert ...

In my previous column, I took a historical approach to delta-sigma modulation with the single-slope converter (May 8, p. 18, ED Online 18747). Jim Williams of Linear Tech responded, and he sent me a ...

In part one, I compared the different Analog to Digital Converters (ADC) and the roles and properties of Delta Sigma ADC’s. I covered a lot of the theory behind these devices, so in this installment, ...

One of the most challenging tasks in Analog to Digital Converter (ADC) design is to adapt the cicuitry to ever new CMOS process technology. For digital circuits the number of gates per square mm app.

All real world signals are analog. The processing is, however, done in the digital domain for most applications. Hence a good interface, an Analog to Digital Converter (ADC) is very much essential.

Isolated sigma-delta (∑-Δ)-based analogue-to-digital converters (ADCs) have become the preferred method for phase current measurement in high performance motor and servo drives. The converters have ...

[Jeri] has had a bear of a time moving up to Valve Software, but electron microscope is safely in her garage (!) and her electronics lab is slowly taking shape. Since she can’t bring out the real-life ...
