Abstract
A voltage supply circuit for an electronic circuit includes a switch configured to selectively connect a supply input of the electronic circuit with a main supply voltage source. An auxiliary voltage supply unit has an auxiliary voltage output coupled to the supply input of the electronic circuit. The auxiliary voltage supply unit is configured to at least temporarily output an auxiliary voltage to the supply input. The auxiliary voltage has a voltage level lower than a voltage level of a main supply voltage supplied by the main supply voltage source.
