  • Circuit for controlling the voltages between well and sources of the transistors of and MOS logic circuit, and system for slaving the power supply to the latter including the application thereof
    Patent number: 5682118
    Abstract: The control circuit includes a reference MOS transistor (24) on which preermined operating characteristics are imposed. Circuitry (21, 22, 23) is provided for comparing an operating characteristic of the transistor (24) with a reference value (V.sub.tnref) so as to produce a control voltage. This voltage, after adaptation, is applied to the transistor (24) so as to fix the threshold voltage (V.sub.th) thereof, in such a way as to maintain the operating characteristics of the transistor (24). This same threshold voltage is then imposed on all the transistors of the logic circuit with which the control circuit is associated. This control circuit makes it possible particularly to reduce the consumption of said logic circuit.
