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 ...

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 ...

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 ...

My last column showed how a single-stage delta-sigma modulator (DSM) produces an output that is a sum of the low pass-filtered input signal and the high pass-filtered quantization noise (see “Part 4,” ...

With 16-bit resolution and SNR of 86 dB, STMicro’s ISOSD61 isolated modulator enhances performance and reliability in industrial motor control. The second-order sigma-delta modulator offers a choice ...

Abstract: This manuscript investigates a sigma-delta–based cycle-skipping modulation strategy for power regulation and current sharing in modular series resonant DC transformers. The method enables ...

Abstract: This paper presents a current-to-digital converter (IDC) based on current-mode continuous-time incremental sigma-delta modulator (CT-I $\Sigma \Delta$) with a capacitive based current ...
