SPICE compact model of controlling electrons of spin qubits using FinFET

2023 , Elias A. Pérez-Rodríguez , Orvañanos-Guerrero, María T. , Tetsufumi Tanamoto

Abstract Semiconductor qubits have garnered attention in the field of device physics. Owing to the limited coherence of electrons and holes, smaller and more compact qubits are desirable. This requirement is aligned with the miniaturization of conventional transistors. In this study, we consider a compact spin qubit based on the FinFET (Fin Field-Effect Transistor) by using the SPICE (Simulation Program with Integrated Circuit Emphasis) simulator. The qubits are represented by the quantum dots (QDs) between the Fin structure. In order to setup the qubit, we have to control the number of electrons through the FinFET. Here, we consider the circuit model of our system by treating the transport properties of the QD and the FinFET as single-electron phenomena. We provide the SPICE simulation results and show the single-electron current as the functions of the FinFET parameters such as the channel length and width including the operation temperature.

An Alternative Method for Shaking Force Balancing of the 3RRR PPM through Acceleration Control of the Center of Mass

2020 , Acevedo, Mario , Orvañanos-Guerrero, María T. , Velázquez, Ramiro , Vigen Arakelian

The problem of shaking force balancing of robotic manipulators, which allows the elimination or substantial reduction of the variable force transmitted to the fixed frame, has been traditionally solved by optimal mass redistribution of the moving links. The resulting configurations have been achieved by adding counterweights, by adding auxiliary structures or, by modifying the form of the links from the early design phase. This leads to an increase in the mass of the elements of the mechanism, which in turn leads to an increment of the torque transmitted to the base (the shaking moment) and of the driving torque. Thus, a balancing method that avoids the increment in mass is very desirable. In this article, the reduction of the shaking force of robotic manipulators is proposed by the optimal trajectory planning of the common center of mass of the system, which is carried out by “bang-bang” profile. This allows a considerable reduction in shaking forces without requiring counterweights, additional structures, or changes in form. The method, already presented in the literature, is resumed in this case using a direct and easy to automate modeling technique based on fully Cartesian coordinates. This permits to express the common center of mass, the shaking force, and the shaking moment of the manipulator as simple analytic expressions. The suggested modeling procedure and balancing technique are illustrated through the balancing of the 3RRR planar parallel manipulator (PPM). Results from computer simulations are reported.

Análisis y optimización de mecanismos para el balanceo dinámico utilizando coordenadas naturales

2022-01 , Orvañanos-Guerrero, María T. , RAMIRO VELÁZQUEZ GUERRERO;40848 , Acevedo, Mario , Velázquez Guerrero, Ramiro , Campus Aguascalientes

Esta tesis explora la optimización del balanceo dinámico en diferentes tipos de mecanismos en el plano para lograr la reducción máxima de las reacciones correspondientes a la Fuerza de Sacudimiento y al Momento de Sacudimiento a través de la redistribución de masas. Las expresiones que definen las reacciones dinámicas en la base del mecanismo se obtienen de manera analítica, gracias al modelado realizado en coordenadas completamente cartesianas. Esto permite ensamblar una matriz de masas constante para todo el mecanismo, en donde además pueden identificarse fácilmente las condiciones de balanceo dinámico. La optimización se lleva a cabo mediante contrapesos calculados utilizando los algoritmos de Descenso de Gradiente y Evolución Diferencial, y se analizan utilizando Frentes de Pareto. En la mayoría de los casos se realizan análisis de sensibilidad, empleando también Frentes de Pareto, que permiten conocer la importancia que cada contrapeso tiene para el balanceo general. Además, se presenta una propuesta para el análisis de las restricciones de la optimización, empleando diagramas de caja. Usando las técnicas propuestas es posible lograr mejoras de hasta el 99.70% en la Fuerza de Sacudimiento y de hasta un 97.56% en el Momento de Sacudimiento, o incluso mayores al 50% en ambos casos cuando se utiliza únicamente un contrapeso.
