DAC variation-tracking calibration |
摘要 |
A method of calibrating a digital-to-analog converter (DAC) is provided. The DAC includes a least-significant bit (LSB) block, and dummy LSB block adjacent to the LSB block. The DAC has a most-significant bit (MSB) block, which includes MSB thermometer macros. The method includes measuring the dummy LSB block to obtain a dummy LSB sum; and calibrating the MSB block so that each of the MSB thermometer macros provides a substantially same current as the dummy LSB sum.
