Devices and methods for improving yield of scalable periphery amplifiers

摘要

Device and methods for improving consistency of operation and therefore yield of sealable periphery amplifiers is described. Amplifier size of the scalable periphery architecture can be adjusted to obtain part-to-part consistency of operating performance as per a defined/desired set of criteria. Amplifier segments of the scalable periphery architecture can be rotated to distribute wear. Further, extra amplifier segments can be implemented on amplifier dies to extend the overall lifetime of amplifiers.

1. A method for controlling an operating performance of a power amplifier, the method comprising:
providing the power amplifier with a plurality of amplifier segments, the plurality of amplifier segments adapted to be turned on or turned off, thus providing the power amplifier with a scalable configuration; providing the power amplifier with a memory storage location; establishing an amplifier operating parameter value associated to a desired operating performance of the power amplifier; establishing a number of amplifier segments to be turned on to obtain the operating parameter value, the established number of amplifier segments being inferior to the plurality of amplifier segments, and storing the established number of segments and the operating parameter value into the memory storage location.
