摘要

<正>This paper presents a 400-MS/s 12-bit CMOS current-steering digital-to-analog converter(DAC).The proposed DAC adapts 6+2+4 segmented architecture and a modified switching scheme to improve dynamic and static performance.The measured spurious-free dynamic range is up to 77.18 dB at 400 MS/s with a 10 MHz input signal.The full-scale output current is 20 mA with a 1.8 V single power supply.The core area occupies 0.6 mm~2 in a standard 1P-6M 0.18-μm CMOS process.
