Delta Sigma Converters: Modulation

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 ...

Delta-Sigma Modulation in CMOS Technology

Delta-sigma modulation has emerged as a pivotal technique in CMOS technology for high-resolution analogue‐to‐digital conversion. By utilising oversampling and noise-shaping strategies, this method ...

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 2)

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 ...

Delta Sigma Converters: Modulation

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 ...
