Abstract:
A circuit includes a startup circuit to provide a charging signal to initiate startup of a reference circuit. The startup circuit includes a detector circuit having a detector current path control, a level shifter having a level shifter current path control, and a charger circuit having a charger current path control. Each of the detector current path control, the level shifter current path control, and the charger circuit current path control enable current flow in the startup circuit when the charger turn-on signal is in the on-state and disable the current flow in the startup circuit when the charger turn-on signal is in the off state.
