A fully differential wideband amplifier for the camera of the Cherenkov Telescope Array (CTA) is presented. This amplifier would be part of a new ASIC performing the digitization at 1-3 GS/s with a dynamic range of 16 bits. Input amplifiers have a voltage gain up to 20 and a bandwidth of 400 MHz. Being impossible to design an 8 GHz GBW fully differential operational amplifier in a 0.35 um CMOS...

In this work a voltage amplifier with a gain-bandwidth (GBW) product of 2.5Ghz utilizing adaptive biasing has been designed, using a standard CMOS technology. The amplifier was tested under gamma-radiation and temperature and features a gain degradation of 4,5 % up to a total dose of 100kGy and 5.6 % within a temperature range of -40 till 130ยฐC. Finally the importance of including the...

The high sensitivity and excellent timing accuracy of Geiger-mode Avalanche PhotoDiodes makes them ideal sensors for particle tracking pixel detectors in high energy physics experiments. However, it is well known that they suffer from dark counts which in practice enlarge the necessary area of the readout electronics. Dark count can be dramatically reduced lowering the bias overvoltage of the...

We present a 16 channel front end prototype implemented in 90nm CMOS IBM process and optimized for 5pF input capacitance. A primary motivation for this project is to study the usefulness of the CMOS technologies below 130nm for front end amplifiers optimized for short strip silicon detectors on Super LHC experiments. On the example of presented design we will show critical aspects of the front...

A number of possible techniques exists for detecting high energy neutrinos from space. The most widely exploited method is the detection of neutrinos in large volumes of water or ice, using the Cherenkov light from the muons and hadrons produced by neutrino interactions with matter around the detector. A photon sensor (photo multiplier tube aka PMT) is housed in a glass sphere (aka Optical...

This work is concerned with the design of analog circuits for processing the signals from deep n-well (DNW) monolithic CMOS sensors. The DNW MAPS approach takes advantage of the properties of triple well structures to lay out a sensor with relatively large area (as compared to standard MAPS) read out by a classical processing chain for capacitive detectors. Recently, a very promising approach...

The LHC at CERN will be upgraded in two phases to increase the design luminosity by a factor of ten. The ATLAS experiment plans to add a new pixel layer to the current pixel detector during the first phase of the upgrade. The optical data transmission will also be upgraded to handle the high data transmission speed. A new driver and receiver ASIC has been designed for this new generation of...
