Abstract

The invention discloses a controllable small-signal voltage source plate, which comprises a power circuit, an upper computer, a serial communication circuit, a single-chip microcomputer, a digital-to-analogue conversion circuit, a reference voltage source circuit, a signal processing circuit and a second-order filter circuit, wherein the power circuit is connected to the single-chip microcomputer; the single-chip microcomputer is connected to the upper computer through the serial communication circuit; the input end of the digital-to-analogue conversion circuit is connected to the single-chip microcomputer and the output end of the digital-to-analogue conversion circuit is connected to the signal processing circuit; the reference voltage source circuit is connected to the digital-to-analogue conversion circuit; and the signal processing circuit is connected to the second-order filter circuit. An output voltage signal can be precisely controlled through the upper computer and the single-chip microcomputer, the manual adjustment of the voltage signal is not needed, and the adjustment is convenient and flexible; through a digital-to-analogue converter, the signal error is reduced and the signal precision is improved; through the second-order filter circuit, the signal jitter is reduced, so that the signal is more stable when the signal is output.

Description

technical field [0001] The invention relates to a voltage source board, in particular to an adjustable small signal voltage source board. Background technique [0002] With the development of science and technology, integrated circuits have been widely used in all aspects of life, bringing great convenience to people's lives. Integrated circuits have the characteristics of small size, high reliability, good performance, and easy mass production. Therefore, in recent years, they have been widely used not only in civilian electronic equipment, but also in military, communication, and remote control. In integrated circuits and related applications, it is often necessary to use small signal voltage source boards to obtain their own required voltage signals. However, the current small-signal voltage source board still has the following shortcomings: 1. The structure is complex, and the size of the output voltage signal can only be adjusted manually, which is inconvenient to oper...
