Abstract: A resistive device which includes at least one strain gauge (12, 14) comprising silicon nanowires, a power supply (16) that has at least one current source (22, 24) able to generate a current (Ibias) for biasing the strain gauge; and acquisition means (18) able to deliver a measurement signal which can be used to determine the variation in the electrical resistance of the gauge is provided. The power supply includes a chopper (26) allowing the biasing current generated by each current source to flow through each gauge only during a fraction of an operating cycle of the device.

Abstract: A regulated voltage generator provides different regulated voltages to an integrated circuit. The regulated voltage generator includes a bandgap reference circuit and at least one gain stage connected to an output thereof. The output voltage of the bandgap reference circuit varies as a function of temperature to compensate for variations in the gain stage made up of first and second transistors. A regulated voltage output by the regulated voltage generator is independent of temperature and of the supply voltage. The value of the regulated voltage is adjusted via a load resistor and via the first and second transistors along with an output transistor of the bandgap reference circuit.
