摘要
Abstract
To address the current source mismatch issue in current-steering DACs,a fuse calibration scheme is proposed.Static calibration technique is used to correct current source mismatch due to process deviations.The core is a fuse preprogramming architecture that allows multiple iterations of preliminary write-and-erase on multiple independent fuse correction units.This meticulous tuning of current output continues until actual testing verifies conformity with established performance criteria,and finally permanent burn-in is performed.The test results of the circuit designed based on the 0.18 μm CMOS process after tape-out show that the DNL of the circuit is reduced from-0.1-0.029 LSB before calibration to-0.5-0.197 LSB after calibration.关键词
