The paper deals with an oscillation based built-in self-test (OBIST) technique to test faults in complex CMOS digital circuits (CCDCs). It focuses on stuck-at-faults, open or short faults, parametric gate delay faults. The method converts complex CMOS digital circuit under test (CCDCUT) to an oscillator and the output pulses are measured for fix time duration. Discrepancy in the number of pulse...

Now–a-days in digital circuits design high speed, high throughput, small silicon area, and at the same time, lowpower consumption of digital circuit is most important things for digital circuit designers. In this paper a novel design method of a low power digital circuit is discussed, where the GATE DIFFUSION INPUT (GDI) technique has been used for the simultaneous generation of digital logic f...

We propose a mapping from digital logic circuits into genetic regulatory networks with the following property: the chemical activity of such a genetic network in vivo implements the computation specified by the corresponding digital circuit. Logic signals are represented by the synthesis rates of cytoplasmic DNA binding proteins. Gates consist of structural genes for output proteins, fused to p...

We propose a hierarchical physical defect-oriented approach for fault diagnosis in combinational digital circuits. We present the circuit as a network of modules. As modules we consider either library components (e.g. complex gates) of digital circuits or arbitrary subcircuits. The higher level fault diagnosis is carried out in two phases. In the first phase, faulty modules are located by cause...

Data acquisition and conversion systems interface between the real world of physical parameters, which are analog, and the artificial world of digital computation and control. With current emphasis on digital systems, the interfacing function has become an important one; digital systems are used widely because complex circuits are low cost, accurate, and relatively simple to implement. In addit...

Physical limitations of Complementary Metal-Oxide-Semiconductors (CMOS) technology at nanoscale and high cost of lithography have provided the platform for creating Quantum-dot Cellular Automata (QCA)-based hardware. The QCA is a new technology that promises smaller, cheaper and faster electronic circuits, and has been regarded as an effective solution for scalability problems in CMOS technolog...
