Abstract

This paper addresses the cost, signal integrity and I/Obandwidth problems in radio-frequency testing by proposing afeature extraction based built-in alternate test scheme. Thescheme is suitable for built-in self-test of radio-frequencycomponents embedded in a system with available digital signalprocessing resources, and can also be extended to implementbuilt-in test solutions for individual RF devices that have accessto a low-end digital tester. The process applies an alternate testand automatically extracts features from the component responseto predict specifications like third order intercept point, 1dBcompression point, noise figure, gain and power supply rejectionratio. The proposed scheme makes use of low-speed low-resolutionundersampling to eliminate the need for a bulkyanalog-to-digital converter and the use of a noise reference forcomparison makes it possible to compensate for imperfectstimulus generation. The simulation results for a 1 GHzdownconversion mixer and a 900 MHz low-noise amplifierpresent an average of 97.3% prediction accuracy of specificationsunder test.
