A previous column, Oversampling Reduces Quantization Errors, included a diagram for, and a short description of, a single-stage sigma-delta analog-to-digital converter (ADC). The ADC produced a stream ...

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 growing availability of digital ICs like microcontrollers, microprocessors, and field-programmable gate arrays (FPGAs) allows developers to use complex digital processing techniques rather than ...

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 ...

Many noncontact temperature-measurement systems use infrared sensors, such as thermopiles, which can detect small amounts of heat radiation. Biomedical thermometers that measure the temperature of an ...

One of the most challenging tasks in Analog to Digital Converter (ADC) design is to adapt the cicuitry to ever new CMOS process technology. For digital circuits the number of gates per square mm app.

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 ...

Step-by-step approach to building a CTSD modulator loop. Introducing the analog accumulator. A closer look at oversampling and noise shaping. The clock sensitivity of CTSD ADCs. 1. A closed-loop op ...

It’s a well-known conundrum that while most computers these days are digital in nature, almost nothing in nature is. Most things we encounter in the real world, whether it’s temperature, time, sound, ...

WILMINGTON, Mass.--(BUSINESS WIRE)--Analog Devices, Inc. (Nasdaq: ADI) today introduced a new portfolio of next-generation 16-to-24-bit, ultra-high precision successive approximation register (SAR) ...
