This file type includes high resolution graphics and schematics. Delta-sigma analog-to-digital converters (ADCs) are fascinating—almost mythical in their ability to support low- to medium-speed and ...

Abstract: A method for spurious tone free delta sigma modulator design is presented. The method is based on an analysis of modulator state space orbits and it is applicable to digital modulators ...

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 ...

Abstract: Multi-bit sigma-delta based digital pulse width modulators (DPWM) are used in the control of DC-DC converters in order to achieve high resolution and therefore high output voltage accuracy ...

A delta-sigma converter uses many samples from the modulator to produce a stream of 1-bit codes. The delta-sigma ADC accomplishes this task by using an input-signal quantizer running at a high sample ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

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 ...

The web is filled with introductions to Delta Sigma modulation (also sometimes referred to as Sigma Delta modulation) in the context of Delta Sigma converters. Unfortunately, the ones I’ve looked at ...

The PWM sigma-delta modulator is a special type of 1-bit sigma-delta modulator that produces a pulse width modulated (PWM) output signal with a fixed repetition frequency. A fixed repetition ... The ...

first-order ΔΣ modulator can be simply understood. The basic problem solved by a ΔΣ modulator is this: given a fixed input value ν that lies in the range [-1, 1], the modulator outputs a pulse train ...
