Abstract:
1. A switching device having a signal input, a first control input, and an output, the switching device comprising: a first transistor including a gate, a drain, and a source, wherein the drain of the first transistor is coupled to the signal input; a second transistor including a gate, a drain, and a source, wherein the drain of the second transistor is directly coupled to the source of the first transistor, and wherein the source of the second transistor is coupled to the gate of the first transistor; and a third transistor including a gate, a drain, and a source, wherein the drain of the third transistor is coupled to the signal input, wherein the source of the third transistor is coupled to the output, and wherein the gate of the third transistor is coupled to the source of the first transistor and to the drain of the second transistor, wherein the switching device is configured to receive a signal at the signal input, to provide the signal at the output in a first state without an applied voltage at the first control input, and to isolate the signal from the output in a second state with an applied voltage at the first control input.
