Abstract

The development of digital technologies that are widely used in industry and farming imposes increased requirements on stabilized voltage sources for a whole number of parameters each of which is important in its own way. However, the resolution of analog-to-digital and digital-to-analog converters and, therefore, the entire procedure of digital signal processing cannot be further upgraded without improving such quality indicators of stabilized voltage sources as the stabilization coefficient and the noise level. This article considers a method and a circuit solution for constructing a low-noise source of stabilized dc voltage based on a general-purpose reference voltage source. The proposed solution reduces the output noise of a voltage stabilizer to a level slightly exceeding the natural noise of the best reference voltage source models while increasing the stability of the automatic control system (stability of the output voltage of the compensation stabilizer).

基于通用参考电压源的低噪声直流稳压器

摘要

工业和农业中广泛使用的数字技术的发展对稳定电压源的所有参数提出了更高的要求，每个参数都以自己的方式很重要。但是，如果不提高稳压源的稳定系数和噪声电平等质量指标，模数和数模转换器的分辨率以及数字信号处理的整个过程就无法进一步升级。本文考虑了一种基于通用参考电压源构建低噪声稳定直流电压源的方法和电路解决方案。
