Abstract
In a high-voltage output buffer, a self-adjusting bias generator is provided which is capable of automatically adjusting the applied bias voltages in the output buffer so as to enhance the output buffer performance. Under normal or high supply voltage conditions, the bias generator provides a first set of bias voltages to the series-connected transistors in the output buffer. Under low supply voltage conditions, the bias generator provides a second set of bias voltages to the various series-connected transistors.
