首先引用一下《Delta-Sigma Data Converters . Theory, Design, and Simulation》在序言部分中的两小段话，作为今天的开场白。 “After all, the field of delta-sigma modulation encompasses many diverse disciplines: systems and control ...

Delta-sigma modulation has emerged as a pivotal technique in CMOS technology for high-resolution analogue‐to‐digital conversion. By utilising oversampling and noise-shaping strategies, this method ...

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 ...

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 ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

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 ...

Pulse density modulation is just the analog portion of a delta-sigma analog-to-digital converter (ADC). It coverts an analog signal into a digital density stream. A recent online discussion about it ...

The delta-sigma ADC tackles the application demands of a slow analog signal that requires a high signal-to-noise-ratio (SNR) and wide dynamic range. But, the delta-sigma converter is not the only ...

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, ...

Delta-sigma (ΔΣ) converters may sound complex, but at their core, they are all about precision. In this post, we will peel back the layers and uncover the fundamentals behind their elegant design. At ...
