Abstract

See full text

A system includes a level shifter coupled to a voltage source, a first transistor, and a second transistor. The system also includes a first current source coupled to the first transistor and the second transistor and configured to bias the first transistor and the second transistor. The system includes a slew detector coupled to the voltage source and to the first current source, where the slew detector is configured to detect a change in voltage of the voltage source, and further configured to provide current to the first current source responsive to detecting the change. The system also includes a second current source coupled in parallel to the first current source, where the second current source is configured to provide current to the first current source responsive to a control signal.
