MOS IC crosspoint switch for space division digital switching networks

An MOS IC crosspoint switch for space division digital switching network is described. A sense amplifier for compensation of signal attenuation through the MOS IC switch is also considered. Transmission of a 50-100 Mbit/s bit rate digital signal seems a reasonable design objective on the basis of analysis of a preliminarily fabricated MOS IC switch and the design characteristics of a bipolar IC sense amplifier. The MOS switch and the SA are monolithic integrated. Dynamic test of the subsystem, in which MOS IC switches and bipolar IC SA's are connected in cascaded stages, has indicated that they are capable of 100 Mbit/s return to zero digital signal transmission and 46-dB signal-to-noise ratio.
