Abstract
A device includes a first connection pin, a second connection pin, a third connection pin, and a fourth connection pin. The second connection pin is configured to be connected to a supply voltage. The fourth connection pin is configured to be coupled to a reference voltage. The device further includes a first transistor including: a first gate and a first source/drain coupled to the first connection pin; a second transistor including a second gate and a second source/drain connected to the first transistor; and a third transistor including a third gate, a third source/drain connected to the second transistor, and a fourth source/drain connected to the fourth connection pin. The third transistor is configured to be controlled by a digital signal using the third connection pin. Both the first gate and the second gate are directly connected to the second connection pin.
