Abstract
A switching device includes a first switch and a threshold voltage adjustment circuitry. The first switch is configured to be selectively turned on according to an enable signal, in order to connect a first pin to a second pin. The threshold voltage adjustment circuitry is configured to adjust a voltage level of a bulk terminal of the first switch according to the enable signal and a voltage provided from a power source. In response to the voltage being de-asserted, the threshold voltage adjustment circuitry is further configured to cut off a signal path between the bulk terminal and the power source.
