摘要/Abstract:
本文展示了一个12位400MS/s CMOS工艺的数模转换器。这款数模转换器采用6+2+4的分段结构和优化的开关方案来提升动态和静态性能。在400MS/s采样频率和10MHz输入信号频率的条件下,测试得到的无杂散动态范围达到77.18 dB。电路采用1.8V单电压供电,最大输出电流35mA。芯片采用标准1P-6M 0.18μm CMOS工艺制造,核心面积为0.6 mm2。
This paper presents a 400MS/s 12-bit CMOS current-steering digital-to-analog converter (DAC). The proposed DAC adapts 6+2+4 segmented architecture and modified switching scheme to improve dynamic and static performance. The measured spurious-free dynamic range (SFDR) is up to 77.18 dB at 400MS/s with 10MHz input signal. The maximum full-scale output current is 35mA with 1.8V single power supply. The core area occupies 0.6 mm2 in a standard 1P-6M 0.18μm CMOS process
