| How to inject charge? |
* Answer
| When the switch is switched from on to off, the operating state of the M()S tube is switched from the variable resistance region to the cutoff region.When the switch is turned on, the MOS transistor is in the variable resistance region. At this time, there is a conductive channel filled with majority carriers, and these carriers constitute a current I under the action of the source/drain voltage V吣..When a capacitor is connected to the source and drain regions, charge injection causes a change in the voltage of the source and drain regions. |
