Abstract: A driving circuit for controlling a MEMS oscillator includes a digital conversion stage to acquire a differential sensing signal indicative of a displacement of a movable mass of the MEMS oscillator, and to convert the differential sensing signal of analog type into a digital differential signal of digital type. Processing circuitry is configured to generate a digital control signal of digital type as a function of the comparison between the digital differential signal and a differential reference signal indicative of a target amplitude of oscillation of the movable mass which causes the resonance of the MEMS oscillator. An analog conversion stage includes a ?? DAC and is configured to convert the digital control signal into a PDM control signal of analog type. A filtering stage of low-pass type, by filtering the PDM control signal, generates a control signal for controlling the amplitude of oscillation of the movable mass.

Abstract: 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 switching circuit is connected between each bit line and a corresponding column output. The switching circuit is controlled to turn on to generate the analog signal dependent on the computational weight and for a time duration controlled by the coefficient data signal. A column combining circuit combines (by addition and/or subtraction) and integrates analog signals at the column outputs of the biasing circuits. The addition/subtraction is dependent on one or more a sign of the coefficient data and a sign of the computational weight and may further implement a binary weighting function.

Abstract: A flash analog-to-digital converter (ADC) receives an input control signal and performs coarse tuning of a frequency of an output signal, produced between first and second nodes having an inductance coupled therebetween. The flash ADC quantizes an operating frequency range for the output signal produced between the first and second nodes as M·?f, where M is an integer from 0 to N?1, where N is a number of intervals into which a frequency range for the output signal is divided, and where ?f is a resulting frequency step produced by the quantizing. The value of M is generated based upon the input control signal and a word controlling switches of a plurality of switched capacitance circuits associated with the first and second nodes to close ones of those switches associated with the control word to coarsely tune the frequency of the output signal.

Abstract: Disclosed herein are improved supporting structures for heart valve prostheses that are collapsible to a low profile for delivery to the implantation site at the native heart valve. For example, the improved heart valve prostheses may be collapsed for minimally invasive delivery and then deployed/expanded at the native heart valve (e.g., mitral, aortic) for implantation. Advantageously, the collapsed configuration permits delivery through a small incision in the patient and also inhibits suture entrapment of the valve posts during implantation. The supporting structure includes an annular portion and a plurality of post members arranged along the annular portion that are collapsible for delivery and expandable for implantation. Also provided herein are delivery components that allow for delivery of the prosthesis.
