Current self-checking regulation circuit based on voltage calibration

A current self-checking regulation circuit based on voltage calibration, comprising:

• a reference group current mirror unit;
• a detection and regulation unit;
• a regulation group current mirror unit;
• wherein the detection and regulation unit comprises an analog to digital conversion module, a data communication module, a microcontroller and a detection resistor module;
• wherein a second end of the detection resistor module is connected to a second end of a first resistor, the second end of the detection resistor module and the second end of the first resistor are connected to a ground potential;
• the first end of the detection resistor module is connected to a switch and to the analog to digital conversion module;
• a reference voltage is applied to the first end of the first resistor;
• the switch is first connected to the reference group current mirror unit followed by a connection to the regulation group current mirror unit;
• wherein a current value is generated by the detection and regulation module based on the differences between the current from the reference group current mirror unit and the regulation group current mirror unit such that the current value does not fluctuate even if the resistance value of the detection resistor module fluctuates.
