Post-Production Adaptation Of Rf Circuits For Application-Specific Performance Metrics

Wireless Revolution V. 2 in the form of Internet of Things (IoT) necessitates development of RF on rapidly evolving manufacturing processes using a small team of engineers. These processing nodes are tuned for digital performance and typically present with higher process variations. Manufactured RF devices either need to include larger margins to guarantee performance or be tuned post-manufacture to recover the performance. In this paper, we present a set of design principles for RF devices that can be adapted post-production for specific needs of the target application. Post-production tuning lifts the design burden from engineering efforts to measurement and calibration at the production test time.
