This paper deals with the voltage stability problem associated with radial distribution networks. Two load models are studied: the full load flow model (FLFM) and the equivalent generic single-line model (EGSLM). Optimization is then carried out to find the optimal capacitor size that minimizes some costing function, and finally several capacitor placement techniques are studied.

Capacitors are important components in many integrated circuits. They serve numerous roles in analog and mixed signal circuits, including switched capacitor filters and sampleand-hold circuits. In addition, capacitors provide a vital role in the decoupling of microprocessors, digital signal processors, and microcontrollers from power supply variations. Traditional integrated circuit capacitors ...

The governing equations which are considered in two-dimensional cylindrical fluid simulations argon discharge with parallel resonance antenna are the continuity equation, the momentum equation with drift-diffusion approximation, the energy balance equation for electrons, the wave equation for azimuthal induced electric field, and Poisson equation for electrostatic electric field [1]. The power ...

Characterization was performed on the application of atomic layer deposition (ALD) of hafnium dioxide (HfO2) and aluminum oxide (Al2O3), and plasma-enhanced chemical vapor deposition (PECVD) of silicon nitride (Si3N4) as metal–insulator–metal (MIM) capacitor dielectric for GaAs heterojunction bipolar transistor (HBT) technology. The results show that the MIM capacitor with 62 nm of ALD HfO2 res...

How Big is a one -Farad capacitor? Would you believe less than a cubic inch? Conventional wisdom and poorly done cartoons notwithstanding, a new capacitor technology is now available that crams incredible capacitance values into very small volumes. As Fig. 1 shows, these are called double -layer capacitors. They are both reasonably priced and available from distributor stock. For instance, a 1....

Efficient wireless energy transfer between two inductor-capacitor circuits has been demonstrated by applying the principles of Coupled Mode Theory to create a system of strongly-coupled, resonating magnetic fields. This paper makes a detailed analyzes how Coupled Mode Theory is used to increase energy transfer between two simple inductor-capacitor circuits.

A new, simple, and low cost frequency independent phase shifter is presented. The design is based on a simple op-amp phase shifter with programmable floating resistor and programmable capacitor. The phase shift can be varied using the programmable resistor. Compensation for the variation in the frequency is achieved using the programmable capacitor. Experimental and simulation results confirm t...

Y-capacitors are used to reduce electro magnetic interference (EMI) in SMPS. This is a capacitor connected between primary and secondary of the SMPS transformer to bypass EMI currents and thus preventing them to reach mains port. Proper connection points for this capacitor are discussed and experimental results are analyzed to verify their effectiveness.

Novel common-mode feedback circuits are proposed for use in pseudo-differential switched-capacitor circuits. They can be implemented by incorporating just four additional capacitors (and switches) for an integrator, and only two additional capacitors for a residue gain amplifier. The circuits are applicable to very low-voltage switched-capacitor stages realized in submicron low-voltage CMOS pro...
