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...
In this paper, a novel methodology for post manufacture tuning of RF circuits is presented. The procedure uses an iterative test-tune-test algorithm that applies a compact alternative test to the DUT and modulates circuit level tuning knobs (bias/supply values) based on the DUT specification values predicted from the test. The test procedure is repeated until convergence to the desired spec values...
In this paper, a novel adaptive calibration technique for advanced RF front-ends is proposed in which sensors are implanted in the transmitter and the observed device test response to a special calibration test is compared against the known golden response to the same. Tuning 'knobs' which are built into the circuit are then used to minimize the error between the observed response and the golden response...
At the present time, coordinated EDA tools for RF/mixed-signal pin test do not exist. In this paper, a CAD tool for efficient production testing of high- performance RF systems using low-cost baseband ATE is presented The CAD tool consists of a custom developed genetic ATPG for spectral (Fourier spectrum) signature-based alternate (to full specification-based tests) test of RF systems and involves...
