Abstract: The invention relates to a circuit comprising a voltage reference (R) and a low-pass filter (F) electrically connected to the voltage reference (R). The filter (F) comprises a stage formed by a stage resistance (Re) electrically connected at a midpoint (M) to a stage capacitor (Ce), the stage resistance (Re) and the stage capacitor (Ce) at least partially defining a time constant of the filter and the midpoint (M) carrying the filtered reference voltage (V?ref). The circuit also comprises a transistor (T) and a control circuit (Cde) of the gate of the transistor (T) configured to bias the transistor (T) in conduction when the circuit (1) is turned on, the on-state resistance of the transistor (T) combining with the stage capacitor (Ce) to raise the filtered reference voltage (V?ref) with a settling time constant lower than the filter time constant.

Abstract: The invention relates to an industrial accelerometer, in particular for monitoring the vibration of an industrial machine. The accelerometer comprises a first and a second microelectromechanical integrated circuit arranged on a planar printed circuit, the first integrated circuit constituting a first triaxial sensor capable of supplying acceleration signals along the three measurement axes, the second integrated circuit constituting a second monoaxial sensor capable of supplying an acceleration signal along a single measurement axis. The first and second integrated circuits are arranged on the planar printed circuit so that the single measurement axis of the second sensor is parallel to one of the three measurement axes of the first sensor.

Abstract: The invention relates to an electronic device for measuring a specific quantity, the device having a two-wire interface having two connection terminals intended to be connected to a conductive pair supplying the measuring device and conveying in return an electrical quantity representative of the measured quantity. The device comprises a transducer providing a raw measurement of the determined quantity, a processing stage for conditioning the raw measurement, the processing stage including one input connected to the transducer and one output, a regulator electrically connected to the processing stage. The regulator includes an input port electrically connected to the two connection terminals of the two-wire interface and an output port supplying regulated voltage to the transducer and/or to the processing stage. The device also includes a feedback circuit electrically connected to the regulator input port and to the processing stage.
