This paper presents a test pattern optimization approach using a proper number of seed selection in mixed-mode patterns. In mixed-mode patterns, the test set is assembled from LFSR based pseudorandom and deterministic patterns. The efficiency of this approach is largely determined by the ratio of those test patterns in the final test. The experiment results show that the total number of patterns in this optimized mixed-mode is minimized compared to conventional mixed-mode technique.

The focus of this research is the cryptographic keys generation with low power consumption. The idea of power consumption minimization by using modified structure of LFSR has been proposed. Some pseudorandom non linear pattern generators with low power consumption used in stream cipher cryptography are presented in this paper: the Geffe generator, the Jennings generator, the Beth-Piper stop-and-go generator, the Gollmann cascade stop-and-go generator.

In this paper, supply current testability is examined experimentally for opens and shorts in a general 3 bit resistor string digital/analog converter (DAC). The results show that all of the shorts and the opens are detected by supply current testing, while opens of the MOS switches are not detected. A DFT method for resistor string DACs is proposed in this paper to detect the opens by supply current testing. Also, testability of a resistor string DAC designed with the DFT method is examined. It is shown that all of the targeted shorts and opens in the testable designed DAC are detected by supply current testing.

In this paper, we investigate the impact of the most common catastrophic and parametric faults in photonic systems. We demonstrate, using the example of a photonic correlator, the effectiveness of testing techniques for fault detection in photonic systems. To the best of our knowledge, this constitutes the first attempt to define a fault model and to develop a test methodology for photonic systems.

Flash memories are a type of nonvolatile memory, which are becoming more and more popular for system-on-chip. But, flash memories are suffered by different types of disturb faults. In the present paper, some new disturb faults that may appear in flash memory are proposed. A modifies March algorithm is developed to detect these faults. Finally, an embedded processor-based built-in self-test (BIST) design is implemented for embedded memories. The proposed method utilizes the concept of reusing the processor in SoC environment. By reusing the embedded processor, the area overhead due to BIST can be reduced to a great extent. The area overhead is only due to the circuits required to design memory wrapper cell. The experimental results show that the area overhead due to BIST is less than 1% for a typical 256K flash memory

This paper is concerned with design and an integrated circuit implementation of a multicarrier quadrature phase generator for application in analog spectral synthesis and orthogonal frequency division multiplexing transceiver using amplitude phase shift keying using 0.18/spl mu/ technology. A noble analog or sampled data based rotational quadrature oscillator has been designed for generating quadrature signals. Scheme of multicarrier generation studied includes multiple frequency generation, using regenerative frequency dividers and mixers. Simulation results and performance of multicarrier generation have been presented. This scheme shows very low power consumption than typical method of multi-frequency signal synthesis using IFFT.

We present an eddy-current test (ECT) method for detecting conductive microbeads on a nonconductive substrate. A Helmholtz coil is used to generate an exciting magnetic field. The magnetic fields, generated by eddy-currents in a Pb-Sn microbead, are detected by a spin-valve giant magnetoresistive (SV-GMR) sensor. The experimental results are compared to an analytical solution for the magnetic field over the microbead. Early results for the detection of a grid of microbeads are also presented.

As the technology scales down, the increased wire aspect ratio and the reduced spacing between the individual wires within a bus result in increased cross-coupling capacitances. This increases crosstalk noise and power dissipation particularly in wide data buses. We propose an efficient encoding scheme that eliminates correlated switching (coupling transitions) in 4-bit buses and also minimizes self-transitions among the wires in these data busses. Wider data busses are implemented using these 4-bit bus blocks.

The paper deals with new background calibration technique, which is utilized in new 10-bit low power pipelined ADC. The switched-capacitor approach is used in designed ADC as well. Since portable applications demand for low power consumption, it is one of the most important issues considered in the design. A modified operational-amplifier (op-amp) sharing technique was used to decrease the power usage as well as capacitor scaling approach. To avoid the clock feedthrough from digital part through the switches, the fully differential circuitry was utilized. The operational transconductance amplifier (OTA) was used in design instead of op-amp. The power consumption of the OTA and other analog parts were taken into account in design procedure. The finite op-amp dc gain problem is solved in digital-domain using background calibration. The capacitor mismatch and op-amp offset are compensated in the same manner.
