An output driver circuit (807) that provides more constant slew rates in the presence of process, voltage, or temperature variations that affect performance. An open ended (no feedback) solution is utilized that provides more constant slew rates in spite of PVT variations. A first performance dependent current (203) and a reference current (201) are generated and a third current is generated (205) that is inversely related to performance utilizing the reference current and the performance dependent current. The third current (860, 862) is supplied to a gate of a first transistor circuit (817, 811) forming a portion of the output diver to thereby control the slew rate. |
