The thesis is focused on the design, the development, and the
realization of a new stereoscopic analogue trigger for the MAGIC Telescopes, in order to
increase the detection efficiency at very low energies (< 50GeV) in the VHE domain, where the
main targets are very distant AGNs, Pulsars and GRBs. This novel trigger concept is based on
the analogue sum of signals coming from patches of the camera detector
