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 ...

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 ...

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 ...

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 ...
