摘要： An apparatus includes parallel delay lines, each exhibiting a delay; a first set of switches for each port of a first set of ports, each of which is to selectively couple a port of the first set of ports to first ends of the delay lines; a second set of switches for each port of a second set of ports, each of which to selectively couple a port of the second set of ports to second ends of the delay lines. A signal source generates a series of clock signals that are sequentially time delayed between the first set of switches and the second set of switches, where an input signal at one of the first or second sets of ports travels from the one of the first or second sets of ports to an output port of opposite set of ports over the delay lines.

摘要： A device includes a stack of at least two piezoelectric layers configured to propagate a Lamb wave in a mode having an order corresponding to a number of piezoelectric layers of the stack. The stack includes a first piezoelectric layer and a second piezoelectric layer disposed on the first piezoelectric layer. The first piezoelectric layer has a first cut plane orientation, and the second piezoelectric layer has a second cut plane orientation complementary to the first cut plane orientation. The device further includes an interdigitated transducer (IDT) disposed on at least a top surface of the stack or a bottom surface of the stack. In some embodiments, the device is an acoustic resonator. In some embodiments, the device is an acoustic delay line.

摘要： An integrated circuit is a layered device, on a semiconductor substrate, which contains metal electrodes that sandwich a piezoelectric layer, followed by a magnetostrictive layer and a metal coil. The metal electrodes define an electrical port across which to receive an alternating current (AC) voltage, which is applied across the piezoelectric layer to cause a time-varying strain in the piezoelectric layer. The magnetostrictive layer is to translate the time-varying strain, received by way of a vibration mode from interaction with the piezoelectric layer, into a time-varying electromagnetic field. The metal coil, disposed on the magnetostrictive layer, includes a magnetic port at which to induce a current based on exposure to the time-varying electromagnetic field generated by the magnetostrictive layer.

摘要： A piezoelectric thin-film suspended above a carrier substrate. An input interdigital transducer (IDT) having first interdigitated electrodes is disposed at different locations along the horizontal axis and on the first side of the piezoelectric thin-film. Each opposing pair of the first interdigitated electrodes is to selectively transduce a particular frequency range of an input electrical signal that varies in frequency over time into an acoustic wave of a laterally vibrating mode based on a pitch between electrodes of the opposing pair. An output IDT that includes second interdigitated electrodes is disposed at different locations along the horizontal axis and on the second side of the piezoelectric thin-film. Each opposing pair of the second interdigitated electrodes is to convert the acoustic wave transduced by the respective opposing pair of the first interdigitated electrodes into a compressed pulse.
