ABSTRACT:
An auxiliary voltage generation circuit is part of a high voltage generation and regulation circuit. The auxiliary voltage generation circuit generates an auxiliary intermediate voltage that is coupled to a negative level shifting circuit to reduce the drain-source stress experienced by transistors in that circuit that are in an off state. The auxiliary voltage generation circuit also generates a logic control signal that indicates to a high voltage discharge path to perform either a slow discharge operation or a fast discharge operation.
