Abstract
A digital calibration method, a device, and a true random number generator circuit are provided. In one aspect, the embodiment of the present disclosure uses the digital calibration method to calibrate compensation of a circuit to be calibrated, output of the circuit to be calibrated is sampled and tested multiple times, and whether a current test compensation calibration code value can make the circuit to be calibrated meet specified accuracy is judged based on a probability that the output result is a target result. Through sampling the output of the circuit to be calibrated multiple times, the selected compensation calibration code has higher accuracy.
