Cross-Coupled Charge Pump Synthesis Based on Full Transistor-Level [PDF]

open access: yesAdvances in Electrical and Electronic Engineering, 2019
This paper presents utility for the design of the cross-coupled charge pump, which is used for supplying peripherals with low current consumption on the chip, as the EEPROM or FLASH memories.

Real-time dynamics of the $O(4)$ scalar theory within the fRG approach

open access: yesSciPost Physics, 2022
In this paper, the real-time dynamics of the $O(4)$ scalar theory is studied within the functional renormalization group formulated on the Schwinger-Keldysh closed time path.

Features of Loss of Stability of the Work of Two-Link Mechanisms That Have an Infinite Number of Degrees of Freedom [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2018
Mechanisms consisting of two links, a leading (engine) and a slave (executive body), which are connected by long lines of force, are considered. With the use of the new method, general equations are derived in Laplace images describing the oscillations ...

On qualitative behavior of multiple solutions of quasilinear parabolic functional equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
We shall consider weak solutions of initial-boundary value problems for semilinear and nonlinear parabolic differential equations for $t\in (0,\infty )$ with certain nonlocal terms.

Spectral analysis of an operator associated with linear functional differential equations and its applications

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2000
The spectral set of an operator which is associated with linear autonomous functional differential equations is determined. The consequence is applied to study the admissibility of linear autonomous functional differential equations for the function ...

Three Positive Periodic Solutions for a Class of Higher-Dimensional Functional Differential Equations with Impulses on Time Scales

open access: yesAdvances in Difference Equations, 2009
By using a multiple fixed point theorem (Avery-Peterson fixed point theorem) for cones, some criteria are established for the existence of three positive periodic solutions for a class of higher-dimensional functional differential equations with impulses

Functional derivatives applied to error propagation of uncertainties in topography to large-aperture scintillometer-derived heat fluxes [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
Scintillometer measurements allow for estimations of the refractive index structure parameter Cn2 over large areas in the atmospheric surface layer. Turbulent fluxes of heat and momentum are inferred through coupled sets of equations derived from the ...
