A novel CMOS charge-pump circuit with positive feedback for PLL applications
TL;DR: The design and simulation of a novel CMOS charge-pump circuit for PLL applications that makes use of positive feedback to increase the switching speed and current reuse to minimize the power consumption is presented.
Journal ArticleDOI
Rational Biparameter Homotopy Perturbation Method and Laplace-Padé Coupled Version
Hector Vazquez-Leal,Arturo Sarmiento-Reyes,Yasir Khan,Uriel Filobello-Nino,Alejandro Diaz-Sanchez +4 more
TL;DR: This work presents the rational biparameter homotopy perturbation method (RBHPM) as a novel tool with the potential to find approximate solutions for nonlinear differential equations and concludes that the LPRBHPM and RBHPM methods generate the most accurate approximated solutions.
Proceedings ArticleDOI
Three transistor exponential transconductor
TL;DR: In this article, the authors presented a novel exponential transconductor which is formed with only three NMOS transistors working in weak inversion, and the circuit is biased with a single current source favoring the design of low voltage circuits and can have a bias voltage from 1.2V and lower.
Journal ArticleDOI
Laplace transform-homotopy perturbation method as a powerful tool to solve nonlinear problems with boundary conditions defined on finite intervals
Uriel Filobello-Nino,Hector Vazquez-Leal,Yasir Khan,A. Perez-Sesma,Alejandro Diaz-Sanchez,Victor Manuel Jimenez-Fernandez,Agustín L. Herrera-May,D. Pereyra-Diaz,J. M. Mendez-Perez,J. Sanchez-Orea +9 more
TL;DR: In this article, a Laplace transform-homotopy perturbation method (LT-HPM) was proposed to solve nonlinear differential equations with Dirichlet, mixed, and Neumann boundary conditions.
Journal ArticleDOI
A fully parallel CMOS analog median filter
TL;DR: A fully integrated CMOS implementation of a continuous-time analog median filter that uses two compact analog circuits as building blocks to implement the variable delay and median detection and a new fast technique for parallel image processing is presented.
