In this study, we investigated the impact of pulse quenching effect on the soft error vulnerabilities in combinational circuits. Simulation results illustrate that soft error vulnerabilities could be reduced by 4–16% for the benchmark circuits when the pulse quenching effect is introduced. By adjusting the cell orientations of the quenching cells in the layout, the soft error vulnerabilities co...

The main topic of this paper is to examine the impact on induction machine magnetic noise of a new stator magnetic circuit design. This new design was developed in order to increase AC machine energetic performance by assembling non-segmented shifted grainoriented steel sheets which make it possible to reduce iron losses. Experimental results on induction machine efficiency increase are present...

In this paper, we propose a level shifter circuit capable of handling a wide input voltage range. The circuit is based on a conventional two-stage comparator, and has a distinctive feature in that it operates a current amplification scheme for ultra low-power operation. The proposed circuit can convert low-voltage input digital signals into high-voltage output digital signals. The circuit achie...

We present a monolithic passively Q-switched microchip laser generating 200 ps pulses at a wavelength of 1064 nm with a repetition rate of up to 2 MHz. While maintaining transversal and longitudinal single-mode operation, the pulse energy can be changed from 130 nJ to 400 nJ by varying the pump conditions of the laser. To the best of our knowledge, the repetition rate of 2 MHz is by far the hig...

A 128-channel pulse-swallow frequency synthesizer includes a 3-mW VCO, a 2.2-mW 16/17 dual-modulus prescaler, a 9-b program counter, and a 7-b swallow counter. The circuit is fully integrated with the exception of the loop-filter capacitor. The ECL prescaler incorporates current sharing and circuit stacking techniques to reduce power consumption. Fabricated in a 1m, 20-GHz BiCMOS process, the c...

Machine learning algorithms often rely on continuous updating of large matrices of “synaptic weights” by local “Hebbian” rules. These rules generally involve a multiplication term, which poses a challenge for implementing large scale hardware for machine learning. In this paper, a method for performing these multiplications using memristor-based arrays is proposed, based on the fact that approx...

The digital PWM modulator circuit is capable of varying the duty cycle of the output (PWM) according to the digital input word. A digitally controlled current starved pulse width modulator is described. The current from the power grid to the ring oscillator is controlled by a header circuit. By changing the header current, the pulse width of the switching signal generated at the output of the r...
