In analog and RF device testing, current industry practice is to exhaustively test each device against its specifications, labeling as faulty any devices that do not meet those specifications. At this point, however, nothing is done with faulty devices—they are simply discarded. Although conservative design can improve yield, increasing variation due to process scaling renders this an insuffici...

In order to perform an on-chip test for characterizing both static and transmission parameters of embedded analog-to-digital converters (ADCs), this paper presents an oscillator-based reconfigurable sinusoidal signal generator which can produce both high and low frequency sinusoidal signals by switching the oscillator into different modes. Analog and digital signals can additionally be produced...

In previous work, we have proposed a framework for blackbox conformance testing of real-time systems based on timed automata specifications and two types of tests: analog-clock or digital-clock. Our algorithm to generate analog-clock tests is based on an on-the-fly determinization of the specification automaton during the execution of the test, which in turn relies on reachability computations....

An on-chip analog mixed-signal testing, compliant with IEEE 1149.4 standard is presented. The testing technique is based on sinusoidal output response characterizations, yielding a complete detection of AC and DC fault signatures without a need for simulation-before-test process. The testing system is an extension of IEEE 1149.4 standard, and affords functionalities for both pre-screening on-ch...

1. Introduction Testing is an important part of design and production of integrated circuits. Such testing of proper function of the circuits consumes a lot of time and resources. It is necessary to set and evaluate lots of parameters in analog testing. It is very inefficient in manual implementation. This testing can be speeded up by using automatic measurements. Professional testing equipment...

Continued improvements of transceiver systems-on-a-chip play a key role in the advancement of mobile telecommunication products as well as wireless systems in biomedical and remote sensing applications. This dissertation addresses the problems of escalating CMOS process variability and system complexity that diminish the reliability and testability of integrated systems, especially relating to ...

This paper presents a resistance matching based selftestable current-mode R-2R Digital-to-Analog Converter (DAC). The Built-In Self-Test (BIST) circuits are employed to observe the current redistributions in the resistance matching branches converted from the R-2R network in the DAC, and then the redistributed currents are transformed to voltages to detect the R-2R network with extra Design For...

Abstract Reservoir permeability, generally determined by experimental or well testing methods, is an essential parameter in the oil and gas field development. In this paper, we present a novel analogy machine learning method to predict reservoir permeability. Firstly, core test production data of other 24 blocks (analog blocks) are counted according DLG block (target block) Jing’an Oilfield, pe...
