Abstract:
A circuit for activating an on-chip voltage generator, the on-chip voltage generator configured to generate an on-chip supply voltage, the circuit comprising:a first voltage sense circuit configured to monitor the on-chip supply voltage, wherein the first voltage sense circuit is configured to detect an occurrence of the on-chip supply voltage being substantially equal to a first threshold;a second voltage sense circuit configured to monitor the on-chip supply voltage, wherein the second voltage sense circuit is configured to detect an occurrence of the on-chip supply voltage being substantially equal to a second threshold, the second threshold having a value different from the value of the first threshold; anda logic circuit coupled to the on-chip voltage generator and the first and second voltage sense circuits, wherein the logic circuit is configured to selectively activate and de-activate the on-chip voltage generator so as to maintain the on-chip supply voltage within a range defined by the first and second thresholds so that in normal operation all transitions between activation and de-activation of the on-chip voltage generator are in response to a detection of an occurrence of the first or second threshold,wherein said all transitions occur between the detections of said first and second thresholds.
