CORRECTION CIRCUIT AND RELATED SIGNAL PROCESSING CIRCUIT, AND CHIP

The application discloses a calibration circuit (140), and the calibration circuit includes: a delay module (180), configured to generate a pre-determined delayed reference signal; a first window function module (101), configured to convert a reference signal into a converted reference signal; a second window function module (102), configured to convert a delayed reference signal into a converted delayed reference signal; a third window function module (103), configured to convert the pre-determined delayed reference signal into a converted pre-determined delayed reference signal; a first delay time computation module, generating a first delay time to be calibrated by receiving the converted reference signal and the converted delayed reference signal; a second delay time computation module, generating a second delay time to be calibrated by receiving the converted reference signal and the converted pre-determined delayed reference signal; and a computation module (190), configured to compute a gain coefficient based on the first delay time to be calibrated and the second delay time to be calibrated.
