Abstract

The invention provides a composite resistor. According to the composite resistor, firstly, an IV conversion circuit is used for converting a current signal into a voltage signal, then a polarity conversion circuit carries out analog-to-digital conversion on the voltage signal based on the voltage signal and a digital-to-analog converter to obtain an analog voltage signal, and the analog voltage signal is converted to obtain an output voltage; at the moment, the output voltage is simultaneously related to a voltage signal (related to a current signal) and an analog voltage signal, so that according to the Ohm's law, the equivalent resistance value of the composite resistor is obtained by dividing the voltage difference between the two ends of the composite resistor by the loop current value, and the current value is counteracted in the calculation process of the equivalent resistance value; as the equivalent resistance value of the composite resistor has no relation with the loop current value and accords with the characteristics of the resistor, and the output voltage value of the digital-to-analog converter can be subjected to accurate program control in a linear range, the resistance value of the composite resistor can be accurately adjusted in the linear range through program control of the digital-to-analog converter, and the resistance value of the composite resistor can be accurately adjusted in the linear range. The development of the circuit technology is promoted.

Description

technical field [0001] The invention relates to the field of resistors, in particular to a synthetic resistor. Background technique [0002] As a common circuit component, adjustable resistors are widely used in all walks of life. There are many specific types of adjustable resistors, such as sliding rheostats. There is a lack of mature adjustable resistors in the prior art, and it is often difficult to realize online The precise adjustment of the resistance value within a certain range limits the development of circuit technology. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Contents of the invention [0004] The object of the present invention is to provide a composite resistor, through the program control of the digital-to-analog converter in the composite resistor, the resistance value of the composite resistor can be precisely adjusted within a linear range, which pr...
