Title:
CIRCUIT PARAMETER DETECTING METHOD AND DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/187044
Kind Code:
A1
Abstract:
A circuit parameter detecting method, comprising: applying a preset excitation signal at an input end of a circuit to be tested, and acquiring one set of actual output data from an output end of said circuit (101); selecting from multiple sets of theoretical output data one set of theoretical output data of highest similarity with the set of actual output data (102); selecting, on the basis of preset correlations between the theoretical output data and parameter values, a set of parameter values corresponding to the selected set of theoretical output data, and making the parameter values in the acquired set of parameter values as detection values for circuit parameters of said circuit (103). Also related is a circuit parameter detecting device. The detecting method and the detecting device allow the detection of the circuit parameters to be free from interference of voltage changes in said circuit, thus increasing the accuracy of circuit parameter detection and reducing requirements on the detection environment.
