Resumo

The development of digital technologies that are widely used in industry and agriculture imposes increased requirements on the reference voltage sources for a variety of parameters, each of which is important. However, further enhancement of the resolution of analog–digital and digital–analog converters and, hence, the digital signal processing as a whole, is impossible without improving such the noise level quality index of reference voltage sources. This work describes a method and circuit design for constructing a low-noise source of stable dc voltage on the basis of typical microelectronic circuits of voltage stabilizers. The developed circuit design provides a reduction in the output noise level of the reference voltage sources made based on such microelectronic circuits of voltage stabilizers up to the level of intrinsic noise of the operational amplifiers used in the developed device. The developed source of stable dc voltage is characterized by inversion of the output voltage polarity relative to the output voltage polarity of the microelectronic circuit of the voltage stabilizer that is used.
