就是图中M1管子,论文的描述是M1 isolates the gate of the output biasing transistor M5 from the low impedance node of the bias current mirror network (M7,M8).
看起来貌似和在较高频率下驱动M5有关,而且依靠的是M2和C2。
原文粗略的说了一下:This makes it possible to drive M5 with signals at high frequencies by means of capacitor C2 and, during negative slewing, by means of transistor M2. 但是不太了解原理
多谢指教。
原文是说 this makes it possible to drive M5 with signals at high frequencies by means of capacitor C2 and, during negative slewing, by means of M2. 结合您的说法,这是和C2一起进行低通滤波么?
