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?

Isolated sigma-delta (∑-Δ)-based analogue-to-digital converters (ADCs) have become the preferred method for phase current measurement in high performance motor and servo drives. The converters have ...

The CS5376A is a multifunction digital filter using a low-power signal processing architecture to achieve efficient filtering for up to four Delta-Sigma modulators. By combining the CS5376A with ...

Delta-sigma converters with sinc (sinx/x) digital filters change the signal chain’s complex antialiasing-filter requirements to a simple, first-order, passive filter. With this “easy-to-design” ...

In this paper, we will attempt to explain sigma delta converters with a non-mathematical approach, covering the basic concepts of noise shaping and oversampling, explained with the help of some ...

Sigma-delta converters are in wide use among applications that demand high precision and accuracy. A variant of the sigma-delta architecture, called the continuous-time sigma delta (CT-S?), has found ...

The transition from second-generation (2G) to third-generation (3G) wireless cellular systems requires multi-standard adaptability in a wireless receiver. An important answer to this request is the ...
