Franco Peláez, Francisco Javier ; Zong, Yi ; Agapito Serrano, Juan Andrés | Elsevier Science BV | 2009-11-12Commercial-off-the-shelf (COTS) capacitor-based isolation amplifiers were irradiated at the Portuguese Research Reactor (PRR) in order to determine its tolerance to the displacement damage and total ionising dose (TID). The set of experimental d[...]texto impreso
En esta memoria, se han presentado las características electrónicas de diferentes dispositivos en tecnología CMOS (Switches Analógicos, Circuitos de Supervisión, Amplificadores de Aislamiento y Conversores Analógico-Digitales), incluyendo las de[...]texto impreso
Franco Peláez, Francisco Javier ; Zong, Yi ; Agapito Serrano, Juan Andrés | IEEE-Inst Electrical Electronics Engineers Inc | 2007-08-20Power operational amplifiers were irradiated in a mixed neutron and gamma radiation environment. These experiments showed that the degradation of the power operational amplifiers shares a great deal of characteristics with that of the low signal[...]texto impreso
Franco Peláez, Francisco Javier ; Zong, Yi ; Agapito Serrano, Juan Andrés ; Casas-Cubillos, Juan ; Rodríguez-Ruiz, Miguel Ángel | IEEE-Inst Electrical Electronics Engineers Inc | 2004-07-22Radiation tests on CMOS analog switches were carried out in order to select the most tolerant device for future use in the cryogenic system of the CERN large hadron collider. After irradiation, the devices showed some interesting changes related[...]texto impreso
Franco Peláez, Francisco Javier ; Zong, Yi ; Agapito Serrano, Juan Andrés | IEEE-Inst Electrical Electronics Engineers Inc | 2006-08-28Radiation tests have shown the existence of inactivity windows in analog switches. It means that the devices lose their ability to switch between ON and OFF states if the total radiation dose is placed between two characteristic values. Once the[...]texto impreso
Franco Peláez, Francisco Javier ; Zong, Yi ; Casas-Cubillos, Juan ; Rodríguez-Ruiz, Miguel Ángel ; Agapito Serrano, Juan Andrés | IEEE-Inst Electrical Electronics Engineers Inc | 2005-10Discrete bipolar operational amplifiers were irradiated with neutrons in order to study the evolution of the short circuit currents. Also, this paper explores the effect of the reduction of this current in devices based on operational amplifiers.texto impreso
Franco Peláez, Francisco Javier ; Zong, Yi ; Agapito Serrano, Juan Andrés | IEEE-Inst Electrical Electronics Engineers Inc | 2006-08-28The frequency behavior of a bipolar operational amplifier (op amp) is always expected to worsen when the device is irradiated. In other words, parameters like the slew rate and the gain-bandwidth product are to decrease after either neutron or g[...]texto impreso
Agapito Serrano, Juan Andrés ; Casas-Cubillos, Juan ; Fernandes, Ana C. ; Franco Peláez, Francisco Javier ; Gonçalves, Isabel ; Hernández Cachero, Antonio ; Marques, José G. ; Rodríguez-Ruiz, Miguel Ángel ; Zong, Yi | CERN Publishing Service | 2004-08-13The cryogenic system of the LHC will use Pt-100 sensors to measure temperatures between 40-300K and isolation devices will be used. The selected commercial components must be rad-tolerant since a total radiation dose of 5E12 n/cm2 &100 Gy is exp[...]texto impreso
Franco Peláez, Francisco Javier ; Zong, Yi ; Agapito Serrano, Juan Andrés ; Hernández Cachero, Antonio | IEEE-Inst Electrical Electronics Engineers Inc | 2005-07-11XFET references make up a new kind of voltage references different from the popular band-gap or buried Zener devices. These references are built by means of a reference cell consisting of a couple of p-channel junction field effect transistors w[...]texto impreso
Franco Peláez, Francisco Javier ; Zong, Yi ; Agapito Serrano, Juan Andrés ; Marques, José G. ; Fernandes, Ana C. ; Casas-Cubillos, Juan ; Rodríguez-Ruiz, Miguel Ángel | Elsevier Science BV | 2005-11-20The electronic instrumentation of the Large Hadron Collider (LHC) cryogenic system is expected to receive a large radiation dose (> 10E13 n·cm?2 and 1–2 kGy (Si)) within 10 years of activity so all the electronic devices should tolerate this rad[...]texto impreso
Zong, Yi ; Franco Peláez, Francisco Javier ; Agapito Serrano, Juan Andrés ; Fernandes, Ana C. ; Marques, José G. | Elsevier Science BV | 2006-09-29This paper concentrates on the selection of radiation tolerant isolation amplifiers, which are suitable for the signal conditioners for cryogenic system in the Large Hadron Collider (LHC). The evolution and the results of different commercial is[...]texto impreso
Zong, Yi ; Franco Peláez, Francisco Javier ; Hernández Cachero, Antonio ; Agapito Serrano, Juan Andrés ; Fernandes, Ana C. ; Marques, José G. ; Rodríguez-Ruiz, Miguel Ángel ; Casas-Cubillos, Juan | 2005-07-11This paper describes the evolution of different commercial microprocessor supervisory circuits under neutron and gamma radiation. After the irradiation, the tested devices showed some interesting changes: an increase of supply current and the pe[...]texto impreso
The use of mathematical optimization techniques allows estimating the degradation of the internal components of irradiated CMOS analog switches from their nonlinear resistance and the value of leakage currents at different power supplies voltages.
