A Bound on the Scattering Parameters of Unconditionally Stable N-Ports [PDF]

IEEE Transactions on Circuits and Systems II: Express Briefs, 2023
Unconditionally stable 2-ports exhibit the peculiar property of mapping regions in the passive termination plane into smaller regions in the input plane. Such a contractive behavior is observed also when the number of ports, N, is larger than two, provided the notion of output region is appropriately adjusted.

An unconditionally stable two-stage CMOS amplifier

IEEE Journal of Solid-State Circuits, 1995
This paper describes a two-stage CMOS amplifier that is stable for any capacitive load. This is achieved through the use of an optimized cascoded compensation topology. A new level shifting technique allows independent optimization of drive capability, noise and systematic offset voltage. The circuit is 0.1 mm/sup 2/ in a 2 /spl mu/m technology and has

Gain profiles for conditionally stable and unconditionally stable amplifiers

APMC 2001. 2001 Asia-Pacific Microwave Conference (Cat. No.01TH8577), 2002
Gain profiles along the line joining the USC (unit Smith chart) center and the SC (stability circle) center for conditionally stable and unconditionally amplifiers are important for amplifier design. SC intersects the USC at two invariant points if |k|

An unconditionally stable hybrid numerical method for solving the Allen–Cahn equation [PDF]

Computers and Mathematics With Applications, 2010
We present an unconditionally stable second-order hybrid numerical method for solving the Allen–Cahn equation representing a model for antiphase domain coarsening in a binary mixture. The proposed method is based on operator splitting techniques.

A Compact Unconditionally Stable FDTD Method

IEEE Antennas and Wireless Propagation Letters, 2006
A novel compact unconditionally stable finite-difference time-domain (US-FDTD) method is introduced. This method utilizes proper intermediate field components to simplify the original unconditionally stable Crank-Nicolson (CN) scheme. The unconditionally stability of the proposed compact US-FDTD method is analytically proven.

Generally Unconditionally Stable Difference Operators

SIAM Journal on Numerical Analysis, 1967
u(x, 0) = uo(x), where P(D) is a partial differential operator of order p with respect to x with constant matrix coefficients. We shall study consistent difference operators of the form (2) v(x, t + k) = Eh,kv(x, t) = f(kP(ah))v(x, t), where f(z) is a rational function, h and k are the mesh-widths in x and t, respectively, and where ahV = (ah,lV, , ah ...

An analysis of an unconditionally stable explicit method

Computers & Structures, 1983
Abstract Recently, several semi-implicit methods have been proposed for the time integration of the structural dynamics equations which are unconditionally stable yet explicit in their algorithmic structure. While these methods seem to violate the basic premise of the Courant requirement that the speed of information flow in the discrete model must ...
