.Measurements o~ the high-frequ~ncy noi:e of a silicon double-injection diode result in (i'l)=a• 4kT ( 1/r) ~if With a= 1.04 and m agreement With the literature. A new interpretation demands Nyquist noise with a 121 in these devices at high frequencies. This is in accord with an equivalent circuit derived for the doubleinjection process. Speculations are made on the general validity of Nyquist ...

This paper presents equivalent circuit modeling of active planar reflectors which can be used for the detailed analysis and characterization of reflector performance in terms of lumped components. Equivalent circuit representation has been proposed for PIN diodes and liquid crystal based active planar reflectors designed within X-band frequency range. A very close agreement has been demonstrate...

The equivalent circuit concept derives from the Superposition Principle and Ohm’s Law. Two forms of the equivalent circuit, the Thévenin equivalent and the Norton equivalent, distill any linear circuit into a source and an impedance. The development of these equivalents spans almost seventyfive years, with others than the eponymous people assuming equally important roles. This report describes ...

Numerical simulation models for capacitive, micromechanical inertial sensors are presented. These dynamic, nonlinear models include the contributions of electrical, mechanical, and fluidic energy domains by means of electrical equivalent circuits consisting of lumped, frequency-independent components. The mechanical resonance modes, gap capacitances, gas film damping forces and the electrostati...

Accurate and fast models of the equivalent circuit (EC) elements gapped multiwinding inductors are essential for design galvanically isolated converters, such as Flyback LLC converters. Typically, EC acquired from measurements or time-consuming FEM simulations, both which disadvantageous optimizing magnetic device. This paper proposes a device that exclusively uses impedance matrix elements, i....
