这项工作提出了一个设计的例子，如何建立从传统的运算放大器不同的环形放大器。环形放大器在放大离散时间波形时具有动态带宽特性。在一个180 CMOS工艺的晶体管级模拟的动态带宽的环放大器证明。该实验表明，与运算放大器相比，在低反馈因素下使用时，性能有所提高。这项工作包括如何建立环放大器的性能影响系统级模数转换器设计的讨论。
This work presents a design example of how ring amplifier settling differs from a traditional operational amplifier. Ringamps posses dynamic bandwidth characteristics when amplifying discrete-time waveforms. The dynamic bandwidth of ringamps is demonstrated with transistor level simulations in an 180 CMOS process. That experiment shows increased performance when used in low feedback factors compared to operational amplifiers. This work includes a discussion on how the settling performance of ringamps affects system level analog-to-digital converter design.
