An Analytical Equation for the Oscillation Frequency of High-Frequency Ring Oscillators
IEEE Journal of Solid-State Circuits, 2004An analytical equation for the oscillation frequency of a ring oscillator is derived. The derivation is done using a novel method which does not need to find an expression for the delay of each stage. The resulting equation includes the effect of time-varying parasitics.

IN the article on simultaneous equations published in AIRCRAFT ENGINEERING, Vol. XI, May, 1939, pp. 199–200, the author exploited the powerful process of iteration. In the present article he deals similarly with an iterative method for finding the roots of a determinantal equation. Such a method was first given by Duncan and Collar in their paper “On a

On the Frequency Equations of Combined Systems
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1996Summary: Two primary systems are considered: An \(n\)-mass oscillator and a one-dimensional continuous structure the displacements of which are discretized by its first \(n\) eigenfunctions. If to each of these systems the same spring-mass system is attached for example at their free ends, it may be expected intuitively that the frequency equations of ...

Frequency dependent transport equation for a magnetoplasma
Plasma Physics, 1970The equation for the pair correlation function form the BBGKY hierarchy has been solved for a magnetoplasma under the influence of a weak external force proportional to exp (i omega 1t) using an operator method and a time-periodic ansatz for the one- and two-particle distribution functions.

Integral equation solution of Maxwell's equations from zero frequency to microwave frequencies
IEEE Transactions on Antennas and Propagation, 2000We develop a new method to precondition the matrix equation resulting from applying the method of moments (MoM) to the electric field integral equation (EFIE). This preconditioning method is based on first applying the loop-tree or loop-star decomposition of the currents to arrive at a Helmholtz decomposition of the unknown currents.

Parametric Frequency Analysis of Mathieu–Duffing Equation
International Journal of Bifurcation and Chaos, 2021The classic linear Mathieu equation is one of the archetypical differential equations which has been studied frequently by employing different analytical and numerical methods. The Mathieu equation with cubic nonlinear term, also known as Mathieu–Duffing equation, is one of the many extensions of the classic Mathieu equation. Nonlinear characteristics

THE “escalator” method of solving frequency equations, developed by Morris and Head (Ref. 1), and the natural extension of a Lemma by Professor Temple, together enable simple proofs to be given of two important fundamental theorems:
