  • Patent number: 10019023
    Abstract: A low-dropout regulator with super transconductance structure relates to the field of power management technology. The super-transconductance structure refers to the circuit structure in which the voltage signal is converted into a current signal and amplified with a high magnification. The error amplifier EA in the present invention uses the super transconductance structure. The differential input pair of the error amplifier EA samples the difference between the feedback voltage VFB and the dynamic reference voltage VREF1. The difference is converted into a small signal current, which goes through a first-stage of current mirror to be amplified by K1, and through a second-stage of current mirror to be amplified by K2. The amplified signal is used to regulate the gate of the adjustment transistor MP. The error amplifier EA with the super transconductance structure is used to expand the bandwidth of the error amplifier EA.

  • Publication number: 20180048478
    Abstract: A novel method for performing replication of messages in a network that bridges one or more physical networks to an overlay logical network is provided. A physical gateway provides bridging between network nodes of a physical network and virtual machines in the overlay logical network by serving as an endpoint of the overlay logical network. The physical gateway does not replicate messages from the bridged physical network to destination endpoints in the overlay logical network directly, but instead tunnels the message-to-be-replicated to a designated tunnel endpoint in the overlay logical network. The designated tunnel endpoint in turn replicates the message that was tunneled to it to other endpoints in the overlay logical network.
