Abstract

A voltage selection circuit, including: first and second nodes of application of first and second input voltages; a third output voltage supply node; first and second MOS transistors respectively coupling the first and third nodes and the second and third nodes; and a control circuit capable of keeping the first and second transistors either respectively on and off or respectively off and on, the control circuit including a feedback loop from the third node to the gate of the first transistor and being capable, during a transition phase, of controlling the first transistor in linear operating region to apply a DC voltage ramp to the third node.
