We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...

Noise immunity is becoming one of the most important design parameters for deep-sub-micron (DSM) technologies. Asynchronous circuits seem to be a good candidate to alleviate the problems originatedby simultaneousswitching noise. However, they are also more sensitive than synchronous ones to spurious signal transitions and delay variations produced by crosstalk noise. This paper addresses the pr...

In this paper a technique is presented which improves the noise immunity of TSPC circuit. This technique is compared with other existing techniques. Analysis is carried out both for super and sub-threshold regions of operation. Investigations consider different performance criteria viz. n ooise immunity curve, power consumption, delay, average noise threshold energy (ANTE),

For deep sub-micron (DSM) technology, noise immunity becomes a matter of crucial importance. The absence of a common clock in asynchronous systems helps to reduce the noise produced by signals switching simultaneously. However for crosstalk noise, an asynchronous approach gives no advantage in comparison to synchronous circuits. This paper concentrates on crosstalk noise and suggests a method f...

This paper proposes a built-in self-test (BIST) scheme for noise-tolerant testing of a digital-to-analogue converter (DAC). The proposed BIST calculates the differences in output voltages between a DAC and test modules. These differences are used as the inputs of an integrator that determines integral nonlinearity (INL). The proposed method has an advantage of random noise cancelation and achie...

This paper describes the impact of crosstalk noise on low power design techniques based on voltage scaling. I t is shown that this power saving strategy aggmvates the crosstalk noise problem and reduces circuit noise immunity. A new energy-eficient, noise-tolerant dynamic circuit technique is presented to address this problem. In a 0.35pm CMOS technology and at a given supply voltage, the propo...

As technology scales into the deep submicron regime, noise immunity is becoming a metric of comparable importance to area, timing, and power for the analysis and design of very large scale integrated (VLSI) systems. A metric for noise immunity is defined, and a static noise analysis methodology based on this noise-stability metric is introduced to demonstrate how noise can be analyzed systemati...

Measuring particle size distribution through calculating light scattering intensity is a typical inverse problem. This paper builds an inverse mathematical model based on Mie scattering, deduces the inversion formulas for particle size, and calculates the relative coefficients through programming with built-in functions in MATLAB. In order to improve the accuracy and noise immunity of particle ...
