“…Based on the strong performance of the LHC accelerator, it is anticipated that peak luminosities of two times the design luminosity are likely to be reached before 2018 and perhaps significantly exceeded in the running period until 2022, referred to as LHC Run 3. Therefore, an upgraded pixel detector, referred to as the phase 1 upgrade, is planned for the year-end technical stop in 2016. …”

“…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. …”

“…In order to maintain or exceed its current performance, the CMS pixel detector will be replaced by a new lightweight system with additional detection layers, better acceptance and improved readout electronics. The upgraded pixel detector will provide improved track and vertex reconstruction, standalone tracking capabilities, as well as identification of particles with longer lifetimes, which will be crucial elements of many physics analyses.…”
