  • Patent number: 10270443
    Abstract: Circuits and methods are provided. The circuits and methods are for providing a supply voltage to a dynamic internal power supply node of a group of other circuits. A circuit includes a first transistor and a second transistor, of different channel types, coupled in parallel to a static power supply that supplies a constant power supply voltage. The circuit further includes a magnetic inductor having a first terminal connected to a common node between the first transistor and the second transistor and a second terminal connected to the dynamic internal power supply node, to supply the dynamic internal power supply node with a boosted voltage having a magnitude greater than a magnitude of the constant power supply voltage by resonating with at least one capacitance coupled to the dynamic internal power supply node.

  • Patent number: 10263519
    Abstract: A booster for a digital circuit block provides speed and reliability at lower static power supply voltages, reducing overall power consumption of the circuits. The booster includes a transistor that couples a dynamic power supply node to a static power supply and is disabled in response to a boost clock. An inductor and capacitance, which may be the block power supply shunt capacitance, coupled to the dynamic power supply resonates so that the voltage of the dynamic power supply increases in magnitude to a value greater the static power supply voltage. A boost transistor is included in some embodiments to couple an edge of the clock to the dynamic power supply, increasing the voltage rise. Another aspect of the booster includes multiple boost transistors controlled by different boost clock phases so that the resonant boost circuit is successively stimulated to increase the amount of voltage rise.

  • Patent number: 10242387
    Abstract: Disclosed aspects relate to managing a set of offers using a dialogue. An adaptive profile may be received with respect to a client. The adaptive profile may indicate a set of client profile data, a set of client event data, and a set of client context data. A dialogue may be established with the client based on the adaptive profile. A set of offers may be resolved by an offer management engine based on the dialogue. The set of offers may be presented to the client.
