Abstract: In one embodiment, a regulator circuit for generating a regulated output voltage Vout has an error amplifier using a pair of bipolar transistors at its front end. The error amplifier compares the regulated output voltage to a reference voltage Vref. A precision current source draws a first current through a user-selected set resistance to generate the desired Vref. The regulator circuit controls a power stage to cause Vout to be equal to Vref. The base current into one of the bipolar transistors normally distorts the current through the set resistance. A base current compensation circuit is coupled to the current source to adjust the first current by a value equal to the base current to offset the base current. Therefore, Vref is not affected by the base current. The error amplifier may be in a linear regulator or a switching regulator. The compensation circuit may be used in other applications.

Abstract: Settings are provided by a chassis management controller to an expansion card in a multi-slot server chassis. The chassis management controller in a multi-slot server chassis provides an operating parameter to a server management controller in a server, and the server management controller writes the operating parameter to a port expander of an expansion card installed on the server. The operating parameter is written to the port expander prior to expansion card power up, and the expansion card uses the operating parameter after power up to derive one or more SERDES value. The SERDES value is used to program an ASIC chip comprising a SERDES converter on the expansion card. In one example, the operating parameter is determined by the capabilities of a chassis midplane at the slot where the compute node is installed.
