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.

Abstract: Systems and methods providing for improved voltage regulation of a supply voltage for an integrated circuit are described herein. The voltage regulator circuit includes a feedback circuit coupled to a first current path and adapted to maintain a gate voltage of a feedback transistor substantially constant. A pass device is coupled to a second current path and adapted to receive a signal with a magnitude based on first and second currents supplied by first and second current sources to the second current path. In an embodiment, the first current is a substantially constant current and the second current has a magnitude based on a magnitude of the voltage at the feedback transistor gate and a magnitude of a voltage at an output of the voltage regulator circuit coupled to the pass device.

Abstract: An oscillator utilizes two current sources that have the same temperature and VDD dependency so they generate the same current in changing conditions. Therefore, there is very low VT dependency. The resistor and fringe capacitor temperature coefficient are very low and opposite so they compensate for each other. A comparator with a short period of operation also minimizes VT dependency.
