Patent ID: 7952418

Claim:
A transistor circuit, comprising: a transistor having a gate and a source; a voltage differentiator coupled between the gate and the source of the transistor; wherein the gate of the transistor is coupled to a first Kelvin sense lead; wherein the source of the transistor is coupled to a second Kelvin sense lead; wherein the voltage at the first Kelvin sense lead is compared to the voltage at the second Kelvin sense lead at the voltage differentiator, wherein an output of the voltage differentiator is operable to control the voltage potential between the gate and the source of the transistor, and wherein the output of the voltage differentiator comprises a voltage differential between the voltage at the first Kelvin sense lead and the voltage at the second Kelvin sense lead; and wherein a transition of the transistor to an on state causes the voltage at the first Kelvin sense lead to be higher than the voltage at the second Kelvin sense lead, causing a voltage controlled current source to raise the voltage applied at the gate to prevent the gate from being cut off.
