Digital-to-analog converter calibration method based on digital domain coding remapping

Номер: CN116155285A
Принадлежит:

The invention discloses a digital-to-analog converter calibration method based on digital domain coding remapping. The digital-to-analog converter calibration method comprises an error measurement step and an error compensation step. In the error measurement step, an auxiliary ADC is adopted to measure the cell weight of each DAC, and the cell weight is stored in a weight register. The error compensation step is realized through coding remapping of a pure digital field, an original code word is input and stored in a buffer register, and a successive approximation loop controlled by a finite-state machine is adopted to carry out numeric field comparison for multiple times, so that an inner product value of a mapping result code word and a real DAC cell weight gradually approaches a value of the buffer register; and finally ensuring that the deviation between the output value of the simulation domain and the ideal value is smaller than the weight of the minimum DAC cell.
