Latest Patents

Quandong Li holds a patent for a "Calibration method and calibration system for sampling time adaptation in time-interleaved ADC, medium, and calibrator." This patent describes a calibration method that involves receiving a mismatching delay of one of the sub-channels in the ADC sampling the same input signal. The method identifies a reference channel that does not require calibration and estimates the mismatching delay of the remaining sub-channels based on this reference. It also includes receiving a sampling signal from the current sub-channel to be calibrated and calculating a calibration slope using a linear interpolation algorithm. The result is a calibrated sampling signal output based on the mismatching delay, calibration slope, and a delay calibration coefficient. Quandong Li has 1 patent to his name.
