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?

While some established chipmakers are developing new proprietary process technologies for mixed-signal and analog devices (see "'Sample Wars' And Silicon Energize ADCs," p. 47), other companies are ...

The most common architectures used in modern analog to digital converter (ADC) design are the successive approximation register (SAR), the sigma-delta and the pipeline. Each architecture has its own ...

In my previous article on EDN, The fully Digital radio transmitter: Is it real of more hype?, there was a great deal of commentary about other alternatives with a digital approach to radio. I these ...

The Analog-to-Digital Converter (ADC) is a key component in digital communications receive channels, and the correct choice of ADC is critical for optimizing system design. In this article, we discuss ...

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 ...

Have you ever checked how many entries are in the web for “design buffer for an ADC”? It can be hard to find what you are looking for amongmore than 4 million references. Probably not a big surprise ...

In this article, we highlight one of the most important architectural traits of new continuous-time sigma-delta (CTSD) precision ADCs: the easy to drive resistive input and reference. The key to ...
