Beschreibung
Zusammenfassung:	A switching circuit may include a first series diode, a second series diode, a first shunt diode coupled to the first series diode at a first control node, and a second shunt diode coupled to the second series diode at a second control node. A high voltage supply may generate a high voltage signal to be selectively applied to either the first or second control node. A dc-dc converter may cooperate with the high voltage supply to generate an intermediate bias voltage on the first and second shunt diodes so that the first series diode is reversed biased and the first shunt diode is forward biased when the high voltage control signal is applied to the first control node, and so that the second series diode is reversed biased and the second shunt diode is forward biased when the high voltage control signal is applied to the second control node.
