摘要： A level-shifter circuit receives one or more input signals in an input level domain and includes provides at an output node an output signal in an output level domain shifted with respect to the input level domain. The circuit includes output circuitry including a first drive node and a second drive node that receive first and second logical signals so that the output signal has a first output level or a second output level in the output level domain as a function of at least one of the first and second logical signals. The circuit includes first and second shift capacitors coupled to the first and second drive nodes as well as capacitor refresh circuitry.

摘要： An in-memory computation (IMC) circuit includes a memory array formed by memory cells arranged in row-by-column matrix. Computational weights for an IMC operation are stored in the memory cells. Each column includes a bit line connected to the memory cells. A biasing circuit is connected between each bit line and a corresponding column output. A column combining circuit combines and integrates analog signals at the column outputs of the biasing circuits. Each biasing circuit operates to apply a fixed reference voltage level to its bit line. Each biasing circuit further includes a switching circuit that is controlled to turn on for a time duration controlled by asps comparison of a coefficient data signal to a ramp signal to generate the analog signal dependent on the computational weight. The ramp signal is generated using a reference current derived from a reference memory cell.

摘要： A microelectromechanical mirror device has, in a die of semiconductor material: a fixed structure defining a cavity; a tiltable structure carrying a reflecting region, elastically suspended above the cavity and having a main extension in a horizontal plane; at least one first pair of driving arms, carrying respective piezoelectric structures which can be biased to generate a driving force that causes rotation of the tiltable structure about a rotation axis parallel to a first horizontal axis of the horizontal plane; elastic suspension elements, which elastically couple the tiltable structure to the fixed structure at the rotation axis and are rigid to movements out of the horizontal plane and compliant to torsion about the rotation axis. In particular, the driving arms of the first pair are magnetically coupled to the tiltable structure to cause its rotation about the rotation axis by magnetic interaction, following biasing of the respective piezoelectric structures.

摘要： A system and method for measuring a capacitance value of a capacitor are provided. In embodiments, a resistor is coupled to a terminal of the capacitor. A difference in voltage at the terminal between a first time and a second time during a discharge routine of the capacitor is measured. The discharge routine includes sinking a current through a discharge circuit coupled to the resistor from first to second. Integration of a difference in voltage at terminals of the resistor during the discharge routine between the first and second times is also measured. The capacitance value is computed based on the measured difference in voltage, the measured integration, and the resistance value of the resistor. The health of the capacitor is determined based on a difference between the computed capacitance value and a threshold value.

摘要： A thermographic sensor is proposed. The thermographic sensor includes a plurality of sensing elements each comprising at least one thermo-couple. The thermographic sensor is integrated on a semiconductor on insulator body that is patterned to define a grid suspended from a substrate; for each sensing element, the grid has a frame with the cold joint of the thermo-couple, a plate with the hot joint of the thermo-couple and one or more arms sustaining the plate from the frame. The frames include one or more conductive layers of thermally conductive material for thermally equalizing the cold joints with the substrate. Moreover, each sensing element may also include a processing circuit for the thermo-couple that is integrated on the corresponding frame. A thermographic device including the thermographic sensor and a corresponding signal processing circuit, and a system including one or more thermographic devices are also proposed.

摘要： A first input node receives a first input signal and a second input node receives a second input signal. The first and second input signals are in phase quadrature. An edge detector circuit senses the first input signal and produces a pulsed signal indicative of edges detected in the first input signal. A pulse skip and reset circuit senses the pulsed signal and the second input signal, and produces a reset signal indicative of pulses detected in the pulsed signal while the second input signal is de-asserted. A sampling circuit senses the second input signal and the reset signal, and produces an output signal that is deasserted in response to assertion of the second input signal and is asserted in response to a pulse being detected in the reset signal.

摘要： Power module packaged in a housing accommodating a carrying substrate forming a plurality of connection regions of conductive material. An electronic component is arranged inside the housing, attached to a connection region of the plurality of connection regions. An electrical connector, coupled to the electronic component, extends towards the main surface of the housing and is accessible from the outside of the housing. The electrical connector has a tubular portion forming a pillar fixed to a pin which protrudes from the greater surface of the housing. The housing includes a packaging mass of electrically insulating material that embeds the pillar and blocks it therein.

摘要： At start-up of a microelectromechanical system (MEMS) gyroscope, the drive signal is inhibited, and the phase, frequency and amplitude of any residual mechanical oscillation is sensed and processed to determine a process path for start-up. In the event that the sensed frequency of the residual mechanical oscillation is a spurious mode frequency and a quality factor of the residual mechanical oscillation is sufficient, an anti-phase signal is applied as the MEMS gyroscope drive signal in order to implement an active dampening of the residual mechanical oscillation. A kicking phase can then be performed to initiate oscillation. Also, in the event that the sensed frequency of the residual mechanical oscillation is a resonant mode frequency with sufficient drive energy, a quadrature phase signal with phase lock loop frequency control and amplitude controlled by the drive energy is applied as the MEMS gyroscope drive signal in order to induce controlled oscillation.

摘要： According to an embodiment, a circuit includes a core and low-frequency recovery circuits. The core circuit is configured to bias a resistive sensor used to measure a fly height of a hard disk drive. The core circuit is additionally configured to amplify a high-frequency component of a sensing signal of the resistive sensor, the sensing signal indicating the fly height. The low-frequency recovery circuit is configured to amplify the sensing signal's low-frequency component.
