Lozano Rogado, Jesús ; Franco Peláez, Francisco Javier ; Agapito Serrano, Juan Andrés | Universidad de La Laguna | 2002-09Se propone en esta comunicación un experimento para facilitar que los alumnos comprendan los principios básicos relacionados con los sensores, circuitos acondicionadores de señal y adquisición de datos con un ordenador. El sistema se basa en un [...]texto impreso
Franco Peláez, Francisco Javier ; Lozano Rogado, Jesús ; Santos Blanco, José Pedro ; Agapito Serrano, Juan Andrés | IEEE-Inst Electrical Electronics Engineers Inc | 2003-12Tests on instrumentation amplifiers exposed to neutron radiation have been done. The tested devices were commercial instrumentation amplifiers or designed with rad-tol commercial operational amplifiers. The results show changes in frequency beha[...]texto impreso
Agapito Serrano, Juan Andrés ; Barradas, Nuno P. ; Cardeira, Fernando M. ; Casas-Cubillos, Juan ; Fernandes, Ana C. ; Franco Peláez, Francisco Javier ; Gomes, Paulo ; Gonçalves, Isabel C. ; Hernández Cachero, Antonio ; Lozano Rogado, Jesús ; Martin Barreales, Miguel Ángel ; Marques, José G. ; Paz López, Antonio ; Prata, María José ; Ramalho, Antonio J. G. ; Rodríguez-Ruiz, Miguel Ángel ; Santos Blanco, José Pedro ; Vieira, A. | CERN Publishing Service | 2000-12-01Instrumentation amplifiers and voltage controlled current sources have been designed by using single operational amplifiers (OPA124, TLE2071 and OPA627). Their performance has been evaluated in the laboratory and under neutron radiation. On line[...]texto impreso
Franco Peláez, Francisco Javier ; Lozano Rogado, Jesús ; Agapito Serrano, Juan Andrés | ESA Publications Division | 2003-09-15The behaviour of CMOS R/2R ladder D/A converters when they are irradiated simultaneously with gamma and neutron radiation is described. The converters suffer an increase of the offset error and a reduction of the linearity because of the malfunc[...]texto impreso
Agapito Serrano, Juan Andrés ; Barradas, Nuno P. ; Cardeira, Fernando M. ; Casas-Cubillos, Juan ; Fernandes, Ana C. ; Franco Peláez, Francisco Javier ; Gomes, Paulo ; Gonçalves, Isabel C ; Hernández Cachero, Antonio ; Lozano Rogado, Jesús ; Marques, José G. ; Paz López, Antonio ; Prata, María José ; Ramalho, Antonio J. G. ; Rodríguez-Ruiz, Miguel Ángel ; Santos Blanco, José Pedro ; Vieira, A. | CERN Publishing Service | 2001A study of several commercial instrumentation amplifiers (INA110, INA111, INA114, INA116, INA118 & INA121) under neutron and vestigial gamma radiation was done. Some parameters (Gain, input offset voltage, input bias currents) were measured on-l[...]texto impreso
Lozano Rogado, Jesús ; Franco Peláez, Francisco Javier ; Paz López, Antonio ; Santos Blanco, José Pedro ; Agapito Serrano, Juan Andrés | s.n. | 2001-09-12Se presenta en este trabajo un sistema de instrumentación y medida de parámetros característicos de componentes electrónicos sometidos a radiación de neutrones. El propósito principal de este sistema es obtener sus características de éstos al m[...]texto impreso
Franco Peláez, Francisco Javier ; Lozano Rogado, Jesús ; Agapito Serrano, Juan Andrés | Instituto de Microelectrónica de Barcelona CNM-CSIC | 2003-02-14The control system electronic of the LHC cold mass will require the use of 12-bit parallel input data converters and they must tolerate the radiation that will be generated by the particle beam. In this paper, we show the radiation tests on some[...]texto impreso
Franco Peláez, Francisco Javier ; Lozano Rogado, Jesús ; Agapito Serrano, Juan Andrés | Instituto de Microelectrónica de Barcelona CNM-CSIC | 2003-02-14Total dose & neutron tests on commercial CMOS digital-to-analog converters have been carried out. These results are related to those ones presented in the previous paper. This kind of devices is much more sensitive to ionizing radiation than to [...]
