Abstract
An output buffer and a method provide controlled low noise operation using a current mirror which provides a rapid increase in the gate voltage of an output transistor prior to the gate voltage reaching the threshold voltage of the output transistor and provide a constant current voltage ramp thereafter. In one embodiment, the present invention automatically compensates for normal variations in transistor channel length due to fluctuations of process parameters. In one embodiment, a mechanism for switching off the current mirror is provided to reduce power consumption.
