Abstract: Rail splitting is creating an artificial virtual ground as a reference voltage. It is used to set the signalto match the op amp's "sweet spot." An op amp has the most linear- and distortion-free qualities at that sweetspot. Typically, the sweet spot occurs near the center between the single power rail and ground. In the case ofa number of signals, the virtual ground can control channel DC errors when multiplexing or switching thesignals.

运放电路中的恒流源电路分析方法 普通镜像恒流源、多集电极恒流源、高精度镜像恒流源、高内阻恒流源和镜像微恒流源电路,以及恒流源电路输出电阻的计算等。 分析恒流源电路的方法是: (1)确定恒流源电路中的基准晶体管或场效应管; (2) 计算或确定基准电流; &nbbsp; (4)绘制恒流部分的交流通路,确定恒流源的内阻。 由于恒流源的内阻较大,计算恒流源内阻时不能忽略三极管集电极与发射极之间,或场效应管漏极与源极之间的动态电阻
