  The first Resistive Plate Chambers detectors were developed for cosmic ray
experiments, where low rate capability, good time resolution and low cost per
unit of area were needed. These same features, except for the low rate
capability, were required in the muon spectrometers of the collider experiments
like LHC. For this purpose newRPCdetectors with increased rate capability were
developed. The rate capability improvement has been achieved thanks to the
transition from streamer to saturated avalanche regime, in which the average
charge produced in the gas dicharge is smaller. The price to pay for this
working mode switch is the transfer of the amplification from the detector to
the FE electorinics. The High luminosity LHC and the future colliders will
require even greater rate capability in the muon spectrometer compared to the
current one. For this reason, further improving of the rate capability is
required. The transition from the saturated avalanche to a low saturated
avalanche regime moves in this direction and needs a new front end electronics
with better signal to noise ratio, because the average induced charge on the
electrode is even smaller. The front end electronics design is crucial for the
RPC performances. In this paper we discuss the performances of the RPC detector
changing the front end design and the detector parameters.
