Abstract
In a packaged integrated circuit, the package inductance limits the rate at which off-chip current may be varied in response to a change in on-chip current demand of the integrated circuit. The present invention provides an on-chip voltage regulator circuit for regulating multi-cycle voltage fluctuations of an integrated circuit associated with changes in current demand of the integrated circuit. The voltage regulator sources current to prevent an undervoltage conditions and sinks current to prevent an overvoltage condition.
