    Abstract: A MEMS resonator is equipped with a substrate, a moving structure suspended above the substrate in a horizontal plane formed by first and second axes, having first and second arms, parallel to one another and extending along the second axis, coupled at their respective ends by first and second transverse joining elements, forming an internal window. A first electrode structure is positioned outside the window and capacitively coupled to the moving structure. A second electrode structure is positioned inside the window. One of the first and second electrode structures causes an oscillatory movement of the flexing arms in opposite directions along the first horizontal axis at a resonance frequency, and the other electrode structure has a function of detecting the oscillation. A suspension structure has a suspension arm in the window. An attachment arrangement is coupled to the suspension element centrally in the window, near the second electrode structure.

  • Patent number: 10505552
    Abstract: An electronic device disclosed herein includes a locked loop circuit configured to receive a reference signal intended to have an intended frequency, wherein the locked look circuit is intended to generate an intended output signal having an intended frequency equal to the intended frequency multiplied by an intended multiplier. A frequency counter counts a number of pulses of the reference signal during a time window so as to determine an actual frequency of the reference signal. A control circuit determines an actual multiplier for the locked loop circuit that, when multiplied by the actual frequency of the reference signal, causes the locked loop circuit to generate an actual output signal having an actual frequency equal to the intended frequency.

  • Patent number: 10498312
    Abstract: A digital filtering method includes receiving a digital signal, and passing the digital signal through a Pth order comb cascade. The method includes beginning pre-computing of intermediate integrator states of a Pth order integrator cascade as a function of the digital signal, prior to receiving output from a last comb of the Pth order comb cascade. The outputs from each comb of the Pth order comb cascade are then applied to the pre-computed intermediate integrator states to thereby produce a filtered version of the digital signal. The Pth order comb cascade may operate at a sampling frequency, and the pre-computing of the intermediate integrator states is performed at the sampling frequency, while the application of the outputs from each comb of the Pth order comb cascade to the pre-computed intermediate integrator states is performed at a multiple of the sampling frequency.

    Abstract: In an embodiment, a method is provided for controlling a level of a read current in a non-volatile memory that is powered by a supply voltage includes. A model current representative of an actual current able to flow during a readout through a read path of the memory is determined based on the value of the supply voltage. The model current is compared to a reference current having a reference value. A control signal is generated. The control signal is to control the generation of the read current having a level equal to the lowest value between a fraction of the value of the model current and the reference value.
