The calibration method and the calibration circuit effectively calibrate the mismatches between the first signal path and the second signal path of a transmitter by calibrating a plurality of tap coefficients of the FIR filter configured in the second signal path and optimizing the tap coefficients. The calibration and optimization for the tap coefficients of the FIR filter is according to differences between the electrical characteristics the DAC convertor and the LPF in the first signal path and differences between the DAC convertor and the LPF in the second signal path. These differences are obtained when the data transmission has not yet started by the transmitter (that is, when the transmitter is working in a training mode)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibration method and calibration circuit","description":"Disclosed are a calibration method and a calibration circuit.
