谢谢谢谢,这也是我的问题,搞不懂动态失调电阻作用是什么,文章意思是保证第三级两阈值电压之和始终大于电源电压Vdd,可是我没有理解是如何做到的,还有“C1是用来把输入共模点定在VCM”那为什么不可以直接加一恒定电压;还有一个问题文章说当输入大于Vcm时,ring amp第一级反相器的输入端是falls,为什么呀,文章中是这么说的"The simulation shown in Fig. 4 begins as the amplifier emerges from the reset phase. If the overall SC amplifier input, is higher than , the ring amplifier input, initially falls at the beginning of the amplification phase and the gain of the first and the second inverter stages causes the gate voltages, and , of the last stage PMOS and NMOS transistors to hit ground." |
