Modern front-end amplifiers for silicon strip detectors offer fast shaping but consequently are susceptible to input capacitance which is the main contribution to the noise figure. Hence, the amplifier must be close to the sensor which is not an issue at LHC, but a major concern at material budget sensitive experiments such as Belle or the ILC detector.
We present a design of a silicon...

The front end electronic (PMF) of the future ATLAS luminometer is described here. It is composed by a MAPMT and a compact stack of three PCBs which deliver the high voltage, route and readout the output signals. The third board contains a FPGA and MAROC, a 64 channels ASIC which can correct the non uniformity of the MAPMT channels gain thanks to a variable gain preamplifier. Its main role is...
