Delta-Sigma(ΔΣ)转换器听起来可能很复杂，但其核心本质还是在于追求精度。在本文中，我们将层层剖析，揭示其精巧设计背后的基本原理。 许多精密测量系统的核心是Δ-Σ转换器，这是一种专为高精度而设计的架构。它以速度为代价换取分辨率，因此在对精度 ...

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

first-order ΔΣ modulator can be simply understood. The basic problem solved by a ΔΣ modulator is this: given a fixed input value ν that lies in the range [-1, 1], the modulator outputs a pulse train ...

The noise‐shaping successive approximation register (NS‐SAR) analogue‐to‐digital converter represents an attractive hybrid architecture that merges the inherent energy efficiency and simplicity of ...

A delta-sigma converter uses many samples from the modulator to produce a stream of 1-bit codes. The delta-sigma ADC accomplishes this task by using an input-signal quantizer running at a high sample ...

Based on the amount of e-mail I received after Part 3 of this series (Nov. 7, 2008, p. 18; www.electronicdesign.com, ED Online 19948), many of you have already guessed that an incremental integrator ...

Bob Adams is an Analog Devices fellow. He is known for his contributions to the invention of log-domain filters, the design of the first monolithic asynchronous sample-rate converters for digital ...

September 21, 2005-- Only a month after announcing the first set of Sigma-Delta Data Converters, Intrinsix announces the availability of three more sets to round out the family. The first set, ...
