    Abstract: Machine-implemented method for a network device is provided. A temperature (T) of an application specific integrated circuit (ASIC) for the network device is compared with a first threshold value. A receive buffer for the network device is placed in an active state, when T is below the first threshold value, and then increasing available credit to store information at the receive buffer. T is also compared with a second threshold value and when T has reached or exceeded the second threshold value, one or more receive buffers are placed in a reduced power state when one or more receive buffers are not currently storing any information.

  • Patent number: 9112513
    Abstract: A calibration system and method are disclosed that include a first bias current generator configured for generating a first bias current that is proportional to absolute temperature (PTAT) and a second bias current generator configured for generating a second bias current that is complementary to absolute temperature (CTAT). The first and second bias currents are copied, multiplied and then summed into a total output bias current, which can be used to bias an electronic circuit. A temperature coefficient is calibrated by changing a ratio of the first and second bias current contributions to the total output bias current, while maintaining the same total output bias current level for a given temperature.
