环形放大器Ring Amplifier的低功耗性能及其在流水线ADC中的实际应用（适用于MDAC，前仿真无版图技术）,Ring Amplifier环形放大器MDAC的低功耗优势及其在流水线ADC中的应用探索：前沿技术与特性解析,Ring Amplifier 环形放大器 MDACGpdk45nm，电路 testbench 文档最大的特点是功耗比较低，应用于低功耗adc场景。也是近几年的热点研究之一，可应用于流水线ADC的MDAC。Ring Amplifier是由环形振荡器衍生过来的，它身上继承了环形振荡器可以根据CMOS工艺伸缩的特性，同时也能实现轨到轨的输出摆幅，利用最后一级的PMOS管和NMOS管交替导通对大电容负载进行有效充电，而且其结构也比较简单，仅仅由少量的开关、电容和反相器构成。前仿真，无版图,Ring
