Abstract: An energy-harvesting system includes a transducer to convert environmental energy into a harvesting electrical signal. A storage element stores electrical energy derived from conversion of the harvested environmental energy. A harvesting interface supplies an electrical charging signal to the storage element. The harvesting interface is selectively connected to the storage element in response to a control signal. The control signal causes the connection when the harvesting electrical signal exceeds a threshold. Conversely, the control signal causes the disconnection when the harvesting electrical signal is less than the threshold.

Abstract: A differentiator generates a time derivative signal from a time-variable signal. A transconductance amplifier generates a biasing control signal as a function of the time derivative signal. A supply network functions to supply the differentiator and transconductance amplifier. The supply network is driven by the biasing control signal output from the transconductance amplifier. With this configuration, speed of operation of the differentiator and transconductance amplifier vary with the supply provided by the supply network, and the supply is modulated as a function of the received time-variable signal.

Abstract: A circuit includes a clock input node, a first signal input node configured to receive a first modulated signal switching between a first DC voltage and a second DC voltage, a bias circuit, a first output node, a first capacitor, a second capacitor, and switching circuitry coupled to the first capacitor and the second capacitor. Control circuitry is configured to initially set the switching circuitry in a first configuration in response to the first modulated signal having the second DC voltage, thereby charging the first capacitor to the second DC voltage and charging the second capacitor to the first DC voltage, and subsequently set the switching circuitry in a second configuration in response to an edge detected in the clock signal, thereby producing the first threshold voltage at the first output node after charge redistribution taking place between the first and second capacitors.

Abstract: An inertial sensor having a body with an excitation coil and a first sensing coil extending along a first axis. A suspended mass includes a magnetic-field concentrator, in a position corresponding to the excitation coil, and configured for displacing by inertia in a plane along the first axis. A supply and sensing circuit is electrically coupled to the excitation coil and to the first sensing coil, and is configured for generating a time-variable flow of electric current that flows in the excitation coil so as to generate a magnetic field that interacts with the magnetic-field concentrator to induce a voltage/current in the sensing coil. The integrated circuit is configured for measuring a value of the voltage/current induced in the first sensing coil so as to detect a quantity associated to the displacement of the suspended mass along the first axis.

Abstract: An electromechanical memory element includes a fixed body and a deformable element attached to the fixed body. An actuator causes a deformation of the deformable element from a first position (associated with a first logic state) to a second position (associated with a second logic state) where a mobile element makes contact with a fixed element. A programming circuit then causes a weld to be formed between the mobile element and the fixed element. The memory element is thus capable of associating the first and second positions with two different logic states. The weld may be selectively dissolved to return the deformable element back to the first position.
