Each channel consists of a fast transimpedance amplifier with 5 ns peaking time, a constant fraction discriminator (CFD), and a Time-to-Digital Converter (TDC). In order to cope with the rate requirement,

The Gigatracker has to provide precise momentum, time and angular measurements on every single track of the sec- ondary 75 GeV/c hadron beam with a timing precision of 150 ps (rms). To meet these require- ments, three hybrid silicon pixel detector stations will be installed in vacuum. An adequate strat- egy to compensate the discriminator time-walk must be implemented and R&D investigating two different options is ongoing. Two prototypes have been designed in order to have an experi- mental comparison of the performances: one approach is based on the use of a constant-fraction discriminator followed by an on-pixel TDC, while the other one is based on the use of a Time- over-Threshold circuit followed by a TDC shared by a group of pixels.

Together they provide the necessary front end electronics for the CMS electromagnetic calorimeter (ECAL) preshower detector systeAspell,Pm in the LHC experiment foreseen at the CERN particle physics laboratory. The design and measurements of the amplifier realised in a 1.5mm bulk CMOS process as a 16 channel prototype chip are presented. Results show the mean gain and peaking time of <peak_voltage> = 1.74mV/mip, <peak_time> = 18ns with channel to channel variations; s(peak_voltage) = 8% and s(peak_time) = 6.5%. The dynamic range is shown to be linear over 400mips with an integral non linearity (INL)=0.05mV as expressed in terms of sigma from the mean gain over the 400mip range. The measured noise of the amplifier was ENC=1800+41e/pF with a power consumption of 2.4mW/channel. The amplifier can support extreme levels of leakage current. The...

The signal shape was observed using a fast, low-noise transimpedance amplifier. The rise time of the signal obtained for a minimum ionizing particle was faster than 3ns at room temperature. This is in agreement with earlier calculations
