Extremum voltage supply circuit with improved switching

摘要

The present invention relates to a circuit for supplying the extremum voltage among several input voltages, including, for each input voltage, a first bipolar transistor, the base of which receives the input voltage and the emitter of which is connected to a common output supplying the extremum voltage; a first current source for biasing the emitter of the first transistor; and switching means for disconnecting the first source from the first transistor when this transistor is blocked./!
