按照惯例，电路中的电流被认为是从正端流向负端，上电子足以反方向流动的。

By convention, current in a circuit is considered to flow from a more positive point to a more negative point, even though the actual electron flow is in the opposite direction.

将寄生电容非灵敏有源开关电容网络（SCN）划分成若干个子网络，对每个子网络定义了运放负端组元割集；

The parasitic-insensitive active switched capacitor network(SCN) is partitioned into several sub-networks. Each subnetwork is defined as the op. amp.
