Abstract: In an LDO regulator, two feedback loops are created. The first feedback loop includes a high power PNP bipolar power transistor connected in series between the input voltage Vin terminal and the output voltage Vout terminal. The first feedback loop includes a first error amplifier that controls a drive transistor to drive the base of the power transistor such that Vout matches a set voltage Vset. This first feedback loop circuitry uses an operating voltage (the upper rail voltage) that is regulated by a second feedback loop and is approximately 300 mV greater than Vout. As a result, the control circuitry will be powered by a low ripple supply to improve output PSRR. Further, the power transistor is connected such that any noise in the input voltage is a common mode voltage across the base-emitter of the transistor.

Abstract: An egress packet modifier includes a script parser and a pipeline of processing stages. Rather than performing egress modifications using a processor that fetches and decodes and executes instructions in a classic processor fashion, and rather than storing a packet in memory and reading it out and modifying it and writing it back, the packet modifier pipeline processes the packet by passing parts of the packet through the pipeline. A processor identifies particular egress modifications to be performed by placing a script code at the beginning of the packet. The script parser then uses the code to identify a specific script of opcodes, where each opcode defines a modification. As a part passes through a stage, the stage can carry out the modification of such an opcode. As realized using current semiconductor fabrication process, the packet modifier can modify 200M packets/second at a sustained rate of up to 100 gigabits/second.

Abstract: A powertrain system employing multiple propulsion torque actuators is described. A method for controlling the powertrain system includes interpreting a driver request, including determining a driver torque request and a regenerative braking request based upon driver inputs to an accelerator pedal and a brake pedal. A desired request is determined based upon the driver torque request and the regenerative braking request. Torque limits for the powertrain system are coordinated based upon the desired request, the driver torque request, and a previous driver torque request to determine upper and lower output torque limits, and the upper and lower output torque limits are combined with system constraints to generate a final torque request. The final torque request is employed to determine torque commands for the propulsion torque actuators, and the propulsion torque actuators are controlled based upon the torque commands for the propulsion torque actuators.

Abstract: In one embodiment, a router selects a particular peer from an original update group used with an Exterior Gateway Protocol (EGP) such as Border Gateway Protocol (BGP). The original update group includes a plurality of peers of the router that share a same outbound policy and that receive common update messages, from the router, of routing table information. The router determines that the particular peer is a potential slow peer based on a first type of indicia, wherein a slow peer is a peer that cannot keep up with a rate at which the router generates update messages over a prolonged period of time. The router confirms that one or more second types of indicia are consistent with the particular peer being a slow peer. In response to the confirmation, the router determines that the particular peer is a slow peer.

Abstract: A driver circuit for a PNP power transistor in an LDO regulator uses a Class AB (push-pull) buffer to supply the necessary base current to an NPN driver transistor, where the NPN driver transistor has its collector connected to the base of the PNP power transistor. A front end circuit of the driver, coupled to drive the Class AB buffer, uses a current diverting transistor, where a first portion of the current is used to control the pull-up transistor in the Class AB buffer, and the remainder of the current is used to control the pull-down transistor in the Class AB buffer, so the driver is very efficient. The portion of the driver circuit between the input of the driver circuit and the base of the NPN driver transistor is an inverting circuit. The driver can properly operate with an input voltage within two diode drops of ground.
