Intro to Delta Sigma and PWM

关于delta sigma 共总原理，非常有用的东西

当今高新技术不断发展，越来越多的高精度仪器设备对输入电源，特别是对输入交流电源的稳压精度要求越来越高。与此同时，随着我国经济的发展和用电负载的急剧增加，电压波动和波形畸变等供电质量问题日趋突出，不能满足高精度仪器设备的需要，因而就需要在电网和这些设备之间增加高稳压精度、宽稳压范围的交流稳压电源。基于 ...

Abstract: This application note describes how sampling clock jitter (time interval error or "TIE jitter") affectsthe performance of delta-sigma digital-to-analog converters (DACs). New insights explain the importanceof separately specifying low-frequency (< 2x passband frequency) and high-frequenc ...

Abstract: Specifications such as noise, effective number of bits (ENOB), effective resolution, and noise-free resolution inlarge part define how accurate an ADC really is. Consequently, understanding the performance metrics related to noise isone of the most difficult aspects of transitioning from ...
