Patent ID: 8358155

Claim:
A circuit that facilitates proximity communication, comprising: a bootstrap transistor; and a pass-gate transistor; wherein the gate and the source of the bootstrap transistor are coupled to a high voltage; wherein the drain of the bootstrap transistor is coupled to the gate of the pass-gate transistor; wherein a first coupling capacitance exists between the source of the pass-gate transistor and the drain of the bootstrap transistor and a second coupling capacitance exists between the drain of the pass-gate transistor and the drain of the bootstrap transistor; wherein transitioning to a high voltage at the source of the pass-gate transistor causes the first coupling capacitance and the second coupling capacitance to boost the voltage at the gate of the pass-gate transistor higher than the high voltage, thereby enabling the high voltage at the source of the pass-gate transistor to pass to the drain of the pass-gate transistor.
