An analog phase discriminator, based on the two complementary CMOS switches, was proposed to measure the initial phase of the sinusoidal wave. The circuit structure of the phase discriminator and its principle were presented, and the phase computational formula was derived through a series of circuit theories. So the initial phase was acquired directly from the circuit, which covered a wide fre...

Solar cell module reliability is inextricably linked to cell-level reliability. This is particularly so with thin-film technologies. In CdTe, reliability issues historically associate with back contact stability and the use of Cu as an extrinsic dopant. Using a simple approach by which identical cells are heated under open-circuit bias and 1-sun illumination, degradation activation energies of ...

Time redundancy is sometimes an only option for enhancing circuit reliability when the circuit area is severely restricted. In this paper, a time-redundant error-correction scheme, which is particularly suitable for coarse-grained reconfigurable arrays (CGRAs), is proposed. It judges the correctness of the executions by comparing the results of two identical runs. Once a mismatch is found, the ...

The reliability of nano-sized combinational circuits can be estimated by using different techniques, such as mathematical equations, Monte Carlo simulations, algorithmic approaches, and combinations of these. Commonly used equations are functions of gate count, and of the reliability and number of devices that make up the gates. The aim of this paper is to present a(n alternative) neural-based ...

As far as the design of SPDs is concerned, the need exists for simplifying its circuit structure in fulfilment of the prerequisite condition of protective reliability. The circuit simplification for SPDs is of benefit to lower the cost of manufacture and reduce the size of chassis. Considering that the traditional SPD that has been extensively used on single-phase AC power supply lines requires...

Abstract: This paper reports a new pixel circuit suitable for enhancing the reliability of AM-OLED with the a-Si:H TFT backplane and top-anode OLED structure. The propose pixel circuit is composed of 5 a-Si:H TFTs for switching and driving device, and it does not require any complicated drive ICs. The compensation of OLED current against threshold voltage shift of the drive TFT has been verifie...

This paper presents a system which uses the adaptive simulated annealing algorithm to optimize placement of modules (e.g. transistors or subcircuits) and (global) routing between these modules. This is achieved through user-specified performance constraints, precomputed sensitivities of the nodes in the circuit and modeling of substrate effects between modules connected to critical nodes. This ...

Very low temperatures stress a circuit breaker in a complex manner. Mixed-gas circuit breakers were developed for use at temperatures as low as -50C. These breakers utilize a gas mixture of SF6 and CF4 or SF6 and N2 to prevent condensation of the SF6 gas and have been type tested at -50C to ensure travel characteristics, operating times, and gas tightness are acceptably affected. Today’s mixed-...
