Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.
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 ...
Highest accuracy isolated sigma-delta modulator for precision current and voltage measurement in DC/AC power conversion applications such as motor drives, solar and wind inverters.
Pulse density modulation is just the analog portion of a delta-sigma analog-to-digital converter (ADC). It coverts an analog signal into a digital density stream.
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 ...
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 ...
For motor control and industrial process control, Texas Instruments' ADS1204 quad delta-sigma modulator enables direct connection to transducers or low-level signals.
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 ...
(To review the basics of sigma delta ADCs, read The basics of sigma delta analog-to-digital converters. To calculate the signal and the noise frequency that can be used as a stimulus for the ADC ...
The sigma delta modulator have a salient feature of shaping the noise, such that noise reduces from the band of interest resulting in high accuracy in comparison to other converters and high ...
This articles addresses the issues of how to design effective delta-sigma modulators for wireless receivers that need to support GSM, DECT, and wideband CDMA (W-CDMA) operation. A single-loop ...
