El esquema propuesto incluye diversos elementos diferenciadores: ha sido diseñado específicamente para minimizar el ruido electrónico y coexistir en la misma placa de circuito impreso que la lógica digital minimizando la contaminación por el ruido que esta genera; utiliza amplificadores operacionales de un modo no convencional para conseguir señales de polaridades opuestas con gran precisión y propone un método para maximizar la carga entregada a la electrónica en el caso particular del calorímetro de LHCb. El documento arranca con una introducción al experimento, los denominados shapers y su utilización el física de altas energías para luego describir en detalle las fases de diseño, prototipado y medición de resultados haciendo especial hincapié en la compatibilidad electromagnética, la integridad de señal y la minimización del ruido.Universitat de BarcelonaHerms Berenguer, AtilàHerms Berenguer, AtilàUniversitat de Barcelona.

description The objective of this thesis is to present a proposal for the analogue signal processing chain needed for the LHCb calorimeter upgrade improving the design used originally. The design contains several novelties: the system was designed with low noise in mind from the beginning, it is made to have good immunity to interferences stressing the fact that the board will be shared with large digital circuits, differential operational amplifiers are used in a non-standard way as a mean to obtain opposite polarity signals for the signal treatment and a way to increase the available signal in the front end electronics is proposed. The thesis starts with a brief introduction to the detector and its environment. This is followed by an explanation of the use of shapers in high energy physics detectors and the constraints that the shaper must address in the LHCb calorimeter. This leads to a chapter where the circuit design is explained starting from the analysis of the original circuit and its flaws. Once the original circuit and the restrictions are understood the different parts of the circuit are explained showing the key points of each one.
