Abstract
Circuitry is provided for controlling current in an electronic circuit by determining a rating of the electronic circuit in response to a measured propagation of a signal during a fixed period of time and by controlling current through an output node of the electronic circuit in response to the rating. The current may be controlled by magnitude or by rate of change with respect to time. By controlling current in response to the rating, timing disparities between and within electronic circuits are reduced, and signal noise in an electronic circuit is reduced by lowering unnecessary amounts of current driving the output node and/or by lowering unnecessarily high DI/DT rates of change in current driving the output node.
