Abstract

The development of digital technologies that are widely used in industry and agriculture places high demands on voltage reference sources for a number of parameters, each of which is important in its own way. However, a further increase in the resolution of analog-to-digital and digital-to-analog converters and, therefore, of all digital signal processing is impossible without an improvement in such a quality indicator of reference voltage sources as the noise level. In this paper, we discuss the method and schematic solution of designing a low-noise source of stable dc voltage base on standard integrated circuits of voltage stabilizers. The schematic solution provides an ability to reduce the output noise level of the corresponding reference voltage sources to a level slightly higher than the intrinsic noise level of operational amplifiers used as a part of the device block circuits, maintaining the polarity and stability of the device output voltage relative to the output voltage of the used integrated circuit of a voltage stabilizer, and reduction in capacitance of used capacitors compared with known circuit solutions.

电压源输出噪声水平降低两级

摘要

在工业和农​​业中广泛使用的数字技术的发展对电压参考源提出了许多参数的高要求，每个参数以其自己的方式很重要。但是，如果不改进诸如噪声电平之类的参考电压源的质量指标，就不可能进一步提高模数转换器和数模转换器的分辨率，因此不可能提高所有数字信号的分辨率。在本文中，我们讨论了基于稳压器标准集成电路设计稳定直流电压低噪声源的方法和示意性解决方案。
