    摘要： Disclosed is a current compensation circuit. During calibration of a compensation current, a digital control circuit delivers a digital signal with values varying over time to a current compensation array, the current compensation array outputs different amounts of compensation current based on the digital signal with values varying over time, the digital control circuit latches a value of the digital signal, which results in a best compensation current, based on influences of the different amounts of compensation current on a parameter to be calibrated, to complete the calibration. Upon and after completion of the calibration, the digital control circuit continuously delivers the digital signal with the latched value to the current compensation array, and the current compensation array outputs the best compensation current based on the digital signal with the latched value.
