Patent ID: 11764816

Abstract:
A method and circuit for controlling the compensation for channel mismatches are used in an electronic device which includes a signal transmission circuit or a signal receiving circuit that have two channels. The electronic device further includes a channel mismatch compensation circuit. The method includes: (A) determining a frequency of a test signal; (B) causing the test signal to pass through the signal transmission circuit or the signal receiving circuit, and measuring an image signal; (C) adjusting a compensation parameter of the channel mismatch compensation circuit to change an amplitude of the image signal; (D) determining, according to the amplitude of the image signal, a target compensation parameter of the channel mismatch compensation circuit, the target compensation parameter corresponding to the frequency of the test signal; (E) repeating steps (A) to (D) to obtain multiple target compensation parameters; and (F) determining a compensation mechanism based on the target compensation parameters.
