Abstract
An apparatus is configured to provide a voltage rising at the output with a programmable slew rate. The apparatus comprises a ramp-up control circuit module for supplying an increasing output voltage that is output to a load circuit. The ramp-up control circuit comprises an amplifier that receives the output of a plurality of selectable mirrored current sources that build up voltage across a capacitor for programming a selected linear slew rate for the increasing output voltage. The apparatus further comprises a glitch filter circuit for stabilizing the increasing output voltage so as to minimize glitches, including current and voltage stress, in the output voltage.
