A DAC calibration technique for high monolithic operation

높은 선형동작을 위한 새로운 DAC 오차보정 기법에 관한 연구

This paper presents a dAC calibration technique for high resolution and monolithic operation. The calibration technique consists of basic source, current memory cell (C.M) and current substrator. Current memory supplies the error current to basic source. Current substrator extracts the error current from the main source. It is simple and needs no special calibration period. The proposed current cell has high calibration performance and guarantees 100MHz operation.
