In this paper, a fast RF BIST-driven post-manufacture tuning methodology for yield improvement of RF transceiver systems is presented. The core algorithms optimize multiple transceiver performance metrics concurrently using a hardware-iterated gradient search algorithm that uses diagnostic BIST data to guide the tuning of circuit and software level parameters. Intelligent ??initial guess?? values...
Design and test of high-speed mixed-signal/RF circuits and systems is undergoing a transformation due to the effects of process variations stemming from the use of scaled CMOS technologies that result in significant yield loss. To this effect, post-manufacture tuning for yield recovery is now a necessity for many high-speed electronic circuits and systems and is typically driven by iterative test-and-tune...
