Abstract
A circuit for regulating resonance in a micro-chip has been developed. The circuit includes micro-chip supply voltage and a ground voltage, and a band-pass shunt regulator that is in parallel to the capacitor across the supply and ground voltages. The regulator will short circuit the supply and ground voltages at a pre-determined frequency to reduce the resonance effect on the micro-chip.
Claims9
An apparatus for regulating resonance in a micro-chip comprising:
- a micro-chip supply voltage line;
- a micro-chip ground voltage line;
- and
- a band-pass shunt regulator connected in parallel with a capacitance across the micro-chip supply voltage line and the micro-chip ground voltage, wherein the shunt regulator shorts the supply voltage and the ground voltage when a voltage in the micro-chip overshoots due to a resonance condition of the micro-chip.
An apparatus for regulating resonance in a micro-chip comprising:
- means for providing a supply-voltage;
- means for providing a ground voltage;
- and
- means for resistively shorting the supply voltage and the ground voltage when a voltage in the micro-chip overshoots due to a resonance condition of the micro-chip.
A method for regulating resonance in a micro-chip comprising:
- connecting a band-pass shunt regulator across a micro-chip supply voltage and a micro-chip ground voltage;
- and
- shorting the micro-chip supply voltage and the micro-chip ground voltage with the band-pass shunt regulator when a voltage in the micro-chip overshoots due to a resonance condition of the micro-chip, wherein the band-pass shunt regulator is a resistive shunt.
