In this paper we propose two buffer circuits for footed domino logic circuit. It minimizes redundant switching at the output node. These circuits prevent propagation of precharge pulse to the output node during precharge phase which saves power consumption. Simulation is done using 0.18μm CMOS technology. We have calculated the power consumption, delay and power delay product of proposed circui...

In this paper, a CMOS realization of the current differencing transconductance amplifier in the low voltage is presented. CDTA circuit can operate in supply rails down to ±0.75V. The low voltage CDTA performs low power consumption and tuning over a wide current range. The proposed circuit is employed in monostable multivibrator using single CDTA with a few external components. The proposed circ...

We study the limiting-amplification capability of a saturated Semiconductor Optical Amplifier (SOA) followed by an optical band-pass filter. We experimentally demonstrate that this simple optical circuit can be effectively exploited to realize a low-power optical limiter for amplitude-modulated pulse trains at multi-GHz repetition rate. We report very large amplitude-modulation-reduction factor...

This paper presents pulse-coupled two bifurcating neurons. The single neuron is represented by a spike position map and the coupled neurons can be represented by a composition of the spike position maps. Using the composite map, we can analyze basic bifurcation phenomena and can find some interesting phenomena that are caused by the pulse-coupling and are impossible in the single neuron. Presen...

This paper proposes a signal processing methodology of communication system and realized that circuits using operational transconductance amplifier (OTA). Two important classes of communication circuit, delta modulator and compander have been designed using that procedure. In the first implementation coded pulse modulation system is demonstrated which employ sampling, quantizing and coding to c...

We report on the direct observation of an attosecond pulse train with a mode-resolved autocorrelation technique. The chirp among the three harmonic fields is specified by analyzing two-photon above-threshold ionization spectra of electrons, resulting in a pulse duration that should be shorter than 450 as, which is, to our knowledge, the first determination of the chirp in the attosecond pulse t...

For reducing both extreme ultraviolet attosecond pulses energy loss in the focusing reflection process and measurement error caused by pulse focusing aberration, as well as improving the operability of pulse spectroscopy monitoring, a combined focusing and flat-field spectrometer analysis system for attosecond pulse is proposed and designed through step-by-step performance optimization. The foc...

In this study, electromagnetic interference testing of microcontroller units (MCUs) under different pulse (EMP) amplitudes, full width at half maximum (FWHM), and angles was carried out on an EMP cell. The coupling path the radiation-type experiment circuit board is random. However, in several experiments with two pins specific to a certain integrated circuit, by measuring voltage MCU pins, sta...

Due to the lack of a standard nanosecond high-voltage pulse generator for sensor calibration, high-stability test system was developed in terms circuit analysis, structural design, and performance test. By establishing equivalent model generator, component parameters five-stage Marx loop one-stage compression steepening unit were simulated. The influence action gap on characteristics output ana...

This paper describes the optical circuit that enables to extract address from a transmitted cell in an all-optical manner. Nonlinear optical loop mirrors (NOLM’s) are used as all-optical switches in order to confirm the operation of the proposed circuit. The control pulses synchronized with address bits are generated from the transmitted cell. The address bits are successfully extracted without...
