Abstract
An apparatus, comprising a transistor having a source/drain node and a gate, and a circuit coupled between the source/drain node and the gate and configured to limit a voltage between the source/drain node and the gate to a clamping voltage such that the clamping voltage is reduced in response to a rising temperature of the transistor. Also, a method, comprising measuring a first temperature, measuring a second temperature, and reducing a clamped voltage between a source/drain node of a transistor and a gate of the transistor responsive to a difference between the first and second temperatures increasing.
