Q. Can you please explain, simply, as to a Bear of Little Brain 1, how sigma-delta converters work? A. By over-sampling, noise shaping and digital filtering. Athens is a beautiful city, with the ...

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 ...

According to Analog Devices (ADI), its AD7403 isolated sigma-delta modulator delivers the highest accuracy for current and voltage measurement in dc-ac power-conversion applications. It achieves an 81 ...

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 ...

Audio D/A converters using sigma-delta conversion techniques are not new, so designers have learned to deal with some of the problems that are inevitable in their implementation. But now Wolfson ...

When working with mixed-signal technology, you will find that the subject of dithering keeps showing up. Most engineers know that averaging “n” samples of an analog-to-digital converter (ADC) will ...
