Abstract
A slew rate controller for a computing system includes a slew rate control module, the slew rate control module further comprising a plurality of sampling modules, each sampling module corresponding to one of a plurality of phase signal inputs, wherein each sampling module receives an input signal, a reference voltage, and the sampling module's respective phase signal input, and wherein each sampling module generates a respective sample of a relationship between the input signal and the reference voltage during a time period indicated by the sampling module's respective phase signal input; and a finite state machine configured to output a slew rate control signal to control a slew rate of the input signal based on the plurality of samples from the sampling modules.
