CSIR-National Physical Laboratory (NPL) India is a National Metrology Institute (NMI), which disseminate traceability of the physical parameters in the country. In the field of microwave, it is one of the apex laboratories to provide traceability. In this paper, the method for precession measurement of effective source reflection coefficient using resistive power splitter and mismatch uncertain...

Nowadays, water and electricity are closely interdependent essential sources in human life that affect socio-economic growth and prosperity. In other words, electricity is a fundamental source to supply a seawater desalination process, while fresh water is used for cooling this power plant. Therefore, mutual vulnerability of water treatment and power generation systems is growing because of inc...

Device mismatch in VLSI degrades the accuracy of analog arithmetic circuits and lowers the learning performance of large-scale neural networks implemented in this technology. We show compact, low-power on-chip calibration techniques that compensate for device mismatch. Our techniques enable large-scale analog VLSI neural networks with learning performance on the order of 10 bits. We demonstrate...

In this paper, power-sharing management control on an AC islanded microgrid is investigated to achieve accurate reactive power sharing. The droop method primarily used manage the active and sharing among DGs in microgrid. However, line impedance mismatch causes unbalanced As a solution consensus-based adaptive virtual controller proposed, where consensus algorithm set mismatch; then correction ...

This paper proposes a 1.5 V 12-b CMOS ratio-independent algorithmic analog-to-digital converter (ADC) based on a capacitor-mismatch insensitive technique. A novel switched-capacitor multiplying digital-to-analog converter (MDAC) with an accurate gain of two is proposed for an algorithmic ADC. The proposed MDAC architecture requires only one opamp in four phases to generate the next residue outp...

the most important factor in donor-recipient matching for hematopoietic stem cell transplantation is their hla typing. for many patients, we can not find a full-matched donor. in high risk patients, one locus  mismatched related donors are suitable alternatives. (1, 2) since the matching of patients and their siblings usually is based on low resolution hla typing, the matching of one locus mism...

Many current-controlled PWM methods have been proposed to design high performance of current control for grid-connected inverters in distributed power generation systems. However none of them have good performance in providing low THD and, at the same time, good robustness to parameters mismatch. Two different current control methods, namely, traditional predictive current controller and robust...

We propose a method for in situ characterization of the photovoltaic module power at standard test conditions, using superposition of the dark current–voltage (I–V) curve measured at the elevated stress temperature, during potential-induced degradation (PID) testing. PID chamber studies were performed on several crystalline silicon module designs to determine the extent to which the temperature...
