  • Patent number: 10595258
    Abstract: In a wireless communication network, base stations exchange user data for a communication service between User Equipment (UE) and wireless network gateways. The network gateways exchange the user data with Internet Protocol (IP) routers. One of the gateways receives a Border Control Protocol (BGP) message from one of the IP routers indicating a performance issue with an IP address. The network gateway associates the IP address with the communication service and transfers signaling indicating a service issue. A management computer receives the signaling and transfers signaling to the base stations to shed the one gateway for the communication service. The base stations then exchange the user data for the communication service between the UEs and the wireless network gateways except for the one gateway. These other gateways exchange the user data for the communication service with the IP routers except for the IP router having the issue.

  • Patent number: 10192630
    Abstract: The track-and-hold circuit includes a switching circuit and a plurality of storage devices. The switching circuit responsive to an input signal applies a representation of the input signal to the storage devices in a track mode and blocks a signal path between the input signal and the storage device in a hold mode such that a transition from the track mode to a hold mode causes the storage devices to store a time sample of the input signal. An acquisition glitch suppression circuit includes a replica amplifier coupled to the switching circuit that senses a differential voltage across the storage devices. A switched clamping circuit clamps inputs of the switching circuit to the sensed differential voltage in the hold mode such that the initial condition of switching transistors of the switching circuit are approximately identical prior to a hold-to-track transition to mitigate differential acquisition glitch.

  • Patent number: 8742797
    Abstract: A double switched track-and-hold circuit includes an input buffer having a first switched amplifier circuit for passing an input signal in a track mode and isolating the input signal from a buffer output in a hold mode, and a track-and-hold core circuit responsive to the input buffer and having a second switched amplifier circuit for tracking the input signal in a track mode and isolating the input signal from a track-and-hold output in a hold mode. The first and second switching amplifier circuits turn off approximately simultaneously during the hold mode to provide enhanced isolation.

  • Patent number: 6954168
    Abstract: A method and apparatus are provided for tracking and holding a voltage. The method includes the steps of providing an external analog voltage on an input of the track and hold circuit during a tracking mode of the track and hold circuit, storing a representation of the sampled external voltage in a storage device of the track and hold circuit, blocking a signal path between the external voltage and the storage device during a holding mode of the track and hold circuit and clamping the input of the track and hold circuit to a predetermined voltage during the holding mode.

  • Patent number: 5519365
    Abstract: A waveguide for surface acoustic waves comprises a substrate for supporting propagation of surface acoustic waves along a direction at a substrate velocity and a dielectric structure disposed above the substrate along the propagation direction of the surface acoustic waves. The structure includes a central portion disposed along the propagation direction, first and second intermediate portions respectively disposed along each opposed side of the central portion along the propagation direction, and first and second outer portions respectively disposed along each outer side of the first and second intermediate portions along the propagation direction. The central, intermediate and outer portions each has first, second and third intrinsic surface acoustic wave propagation velocities along the propagation direction of the surface acoustic waves, respectively and the first velocity is intermediate of the second and third velocities.

  • Patent number: 5420448
    Abstract: A complementary acoustic charge transport circuit element comprises first and second buried channels. Each of the channels is comprised of a piezoelectric semiconductor and each channel has a source through which charge is injected and a drain through which charge is extracted. A transducer propagates an acoustic wave through each channel and the propagated waves transport the charge between the sources and the drains. A source and/or a drain of one channel is connected in parallel with the corresponding souce and/or drain of the other channel. The waves are complementary at the interconnected ones of the sources and/or the drains.

  • Patent number: 4633285
    Abstract: The disclosure is directed to a method and a device for delaying an electrical signal, the method and device being useable in various signal processing applications. A buried channel is formed by disposing a portion of a layer of piezoelectric semiconductor material between confining layers. A surface acoustic wave is established in the piezoelectric semiconductor material. Majority carriers are depleted from the channel, and an electrical signal is injected into the channel. A delayed version of the electrical signal, which had been carried along by the surface acoustic wave, can then be extracted from the channel.
