Design of the Self-Calibrated OJA Converter with Current Source Matrix Stricture

셀프 캘리브레이션 기법을 이용한 행렬 디코딩 D/A 컨버터의 설계에 관한 연구

This paper presents a 6-bit self-calibrated D/A converter designed with current cell matrix structure. This structure is based on the current-cell matrix configuration using a regulated gate cascode current cell with 3-way switch. using from CMOS process and 5V power supply, the simulated conversion rate is 45.78MHz and the average mismatching properties among current sources are reduced to 0.02% and 0.005%, respectively when 1% and 0.5% errors of current sources are considered.
