A multistage operational amplifier includes a transconductor input stage, an output stage, and an intermediate stage. A first Miller capacitor is connected between the input and the output of the intermediate stage. A second Miller capacitor is connected between the input of the intermediate stage ...
17.The designers of these circuits based them on the same concept: a fully integrated, single-die-IC switching regulator and a micropower operational amplifier. 17.些电路的设计者们在设计时都有同样的观念:完整的单一模式集成电路继电器和微功率运放。 18.Ambipolar transistors are attractive for realizing...

operational amplifier (op-amp)运算放大器无疑是模拟电路中最基础最重要的block之一. 这一章我们将review op-amp一些重要参数包括:AOL (open-loop gain), CMR (common-mode range on the input), CMRR (common-mode rejection ratio), PSRR (power supply rejection ratio), output voltage range, current sour...
In addition to amplifier stability considerations, input source resistance values should be low to take full advantage of the low noise characteristics of the amplifier. Thermal noise (Johnson Noise) of a resistor is generated by thermally−charged carriers randomly moving within the resistor creating...
Using a CMFB Amplifier 下图的CMFB形成负反馈环路, 把Output钳位在Vbiasp. 一种CMFB实现方法如下图所示. 当输出Output=Vbiasp, M1和M2流过电流为20uA 当Output上升(+增加), M2电流变小, M1变小, 而流过Vbiasp的PMOS电流变大, VCMFB变大. 形成负反馈来降低Output. ...
