Abstract:
A circuit includes a delay circuit, a transition detector, a pre-driver circuit, and a controller. The delay circuit includes an input for receiving a signal and an output for providing a delayed version of the signal. The transition detector is coupled to the input of the delay circuit to detect a transition within the signal and to provide a look ahead signal to a detector output. The pre-driver circuit includes an input coupled to the output of the delay circuit, a control input, at least one signal output, and a plurality of a bias outputs. The controller is coupled to the detector output and to the control input of the pre-driver circuit and is configured to control bias signals on a plurality of bias outputs to selectively increase a driving strength of signals and biases applied to an output stage in response to the look ahead signal.
