Abstract
A circuit is provided for processing a pseudo-oscillatory signal generated by an oscillating circuit including a comparator and a logic circuit. The oscillating circuit has a first terminal connected to an energy source by a first switch and a second terminal referenced alternately to a potential substantially equal to half the high potential of the power supply and to the low potential of the power supply. This alternate reference is determined by a second switch controlled synchronously with the first switch by the logic circuit.
