Method for controling an analog switch

摘要

The method involves applying a voltage to a gate (51) of a transistor (50) during an on state and applying another voltage to the gate of the transistor during an off state. The former voltage is a sum of input voltage (Vin) and source voltage (Vdd), and the latter voltage is a difference between the input and source voltages. The former voltage is applied by a capacitor (42) and the latter voltage is applied by a capacitor (44). An independent claim is also included for a device for controlling an analog switch.
