Abstract:
Embodiments of a method, a circuit and a system are disclosed. In an embodiment, a discharge protection circuit is disclosed. The discharge protection circuit includes a switch having a capacitive coupling between a gate and a drain of the switch, wherein the capacitive coupling facilitates a capacitively coupled current. The discharge protection circuit further includes a gate network including at least the gate of the switch, a gate control element and a resistor connected to the gate and the gate control element. In addition, the discharge protection circuit includes an electrostatic discharge rail that connects to a diode that is coupled to the gate and the resistor, wherein the capacitive coupling facilitates sinking of at least a part of an electrostatic discharge current via the gate network.
