    摘要： A stacked pre-driver stage and a power amplifier including the stacked pre-driver stage are described. The stacked pre-driver stage comprises stacked pre-drivers arranged in series between a supply voltage and a reference voltage. Each pre-driver includes a pre-driving amplifier, together with MOS transistors. Each pre-driver is subject, in operation, to a voltage difference which is inferior to a maximum allowed use voltage of the MOS transistors with a largely reduced voltage drop across the regulator included in the power amplifier.

    摘要： An apparatus for canceling a signal is disclosed. The apparatus may include an identification code (ID code) generator configured to generate an ID code. The apparatus may also include an ID code injector configured to inject the ID code into at least one of the signal and a processed signal to produce a convolved signal. The processed signal is resulted from a processing of the signal. The apparatus may further include an ID code detector configured to detect at least one of the convolved signal, a transformed signal, and a transformation of the convolved signal. The transformed signal is resulted from the transformation of the convolved signal. The apparatus may further include an arithmetic function configured to remove at least one of the convolved signal and the transformed signal.

    摘要： A method, system, and apparatus are provided for testing a service in a network. A simulated interface is created on a network device by a Network Management Station (NMS). Thereafter, an instruction is received at the simulated interface from the NMS. The instruction comprises a source address, a destination address and other information to test a service. The service is tested on the network device based on the received instruction. A response is generated from the test. The response indicates whether the service is Working as intended between the source address and the destination address. The response is sent from the simulated interface to the NMS.

    摘要： A packet communication device is disclosed. The packet communication device may include a detector configured to detect a characterized content in incoming packets received by the packet communication device. The packet communication device may further include a play-out control configured to perform an adjustment of the incoming packets to produce adjusted packets and output the adjusted packets, if the detector has detected the characterized content in the incoming packets.
