Claim 7:
8. A circuit comprising:
a first transistor including a first control terminal and a first load current path connected between a first contact and a second contact;
a first resistor connected between the first control terminal of the first transistor and the second contact;
a second transistor including a second control terminal and a second load current path connected between the first control terminal of the first transistor and the first contact,
a second resistor connected between the second control terminal of the second transistor and the first contact;
a third transistor including a third control terminal and a third load current path connected between the second control terminal of the second transistor and the second contact; and
a third resistor connected between the third control terminal of the third transistor and the second contact;
wherein the third transistor comprising an intrinsic capacitance coupling the third control terminal of the third transistor to the second control terminal of the second transistor;
wherein the third transistor is configured to operate in a conducting state in response to a voltage produced across the third resistor as a result of a discharge current from the first contact that flows from the second resistor to the third control terminal of the third transistor via the intrinsic capacitance of the third transistor and from the third control terminal of the third transistor to the second contact via the third resistor,
wherein operating the third transistor in the conducting state generates a voltage swing at the second control terminal of the second transistor;
a fourth transistor including a fourth control terminal and a fourth load current path connected between the first contact and the second control terminal of the second transistor, and
wherein the control terminal of the fourth transistor is configured to receive a logic signal.
