或你要用程序来描写这个系统,跟模拟回授放大器Analog Feedback遇到BA≥1就会遇到收敛的问题,虽然用直观来想象电路"稳定"的解必然要满足Closed-Loop Gain = A/(1-BA),但如果有个理想的系统模型迭代用了QucsStudio也是得到无法收敛的结果,必须要满足BA<1才能得到收敛,不知道运算放大器仿真器是怎么跑瞬时响应的...
A low-power, low-noise amplifier with a negative feedback loop is provided. A low noise amplifier (LNA) includes a common gate (CG) amplifier, a common source (CS) amplifier having a gate connected to a source of the CG amplifier, a differential current balancer (DCB) connected to an ...
Black came up with a negative feedback loop, which was designated negative in contrast to the snowballing positive loop of the amplifier. 幸好布莱克设计出了一个负反馈回路,它的作用就是用来抵消放大器的正回路所产生的滚雪球效应。 dongxi.net 6. Negative feedback loop---A closed path of action an...
