Abstract

An output buffer with PVTL compensation includes a PVT sensor, a decider, an output buffer and a leakage compensation circuit. The PVT sensor and the decider is used to detect the PVT corner of the transistors, therefore the output buffer is compensated according to the detecting result to improve the voltage slew rate. In addition, when the leakage happened in the output buffer and cause the gate voltage drift, the leakage compensation circuit provides a compensated current to the output buffer to stabilize the gate voltage of the output buffer to prevent the gate oxide of the output buffer from overvoltage.
