Abstract:
1. An electronic system including at least a first electronic device D 1 with semiconductor components, at least an input terminal, an output terminal, a high supply terminal brought to a high potential V DD , and a low supply terminal brought to a low potential V SS , defining a supply voltage V DD −V SS , wherein said electronic device D 1 has a transfer function H 1 the graphic representation of which as a function of said supply voltage includes three successive ranges, the first range ranging from low values of V DD −V SS to a value V T , called the threshold voltage of the semiconductor components, said first range corresponding to a value h 1 of H 1 that is high and substantially constant, the second range ranging from V T to a value V C2 , corresponding to a sharply sloping decrease in H 1 and the third range extending beyond V C2 , corresponding to a value h 2 of H 1 that is low and substantially constant, wherein said first device D wherein said capacitive element with variable capacitance is a transistor including a gate connected to said output terminal of said first electronic device D wherein said transistor is made in SOI technology, wherein said first device D wherein said transistor is of the N type and wherein its source and its drain are connected to said low supply terminal.
