Dave Van Ess, an apps engineer over at Cypress Semiconductor has a nice article about ADC noise over at Electronic Design. Now me, being an analog curmudgeon, I don ...

Incremental analog-to-digital converters (ADCs) and delta-sigma modulators represent two advanced architectures that have been pivotal in high-precision signal processing. Incremental ADCs convert ...

Delta-sigma converters are ideal for converting signals over a wide range of frequencies from dc to several megahertz with very-high-resolution results. Figure 1 shows the basic topology, or core, of ...

Shown is a simplified continuous-time sigma-delta ADC model, comprising a sigma-delta modulator and a decimation filter. The DT-S? input structure typically implements switched capacitors, and CT-S?

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 ...

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 ...

In part one, I compared the different Analog to Digital Converters (ADC) and the roles and properties of Delta Sigma ADC’s. I covered a lot of the theory behind these devices, so in this installment, ...

A new 18-bit successive-approximation-register (SAR) converter and a 20-bit delta-sigma unit expand the speed and accuracy envelopes for analog-to-digital converters (ADCs). Made by Analog Devices, ...

A circuit that generates a 1-bit pulse density modulated (PDM) signal from analog input. It creates fixed-width pulses in relation to the amplitude of the analog waveform. As the wave amplitude rises, ...
