Large-scale integrated circuits, in particular ASIC's, have an input converter (1) with an emitter follower (2), a reference voltage generator (3) and VCC and VEE voltage supply. When several outputs of ASIC's with an ECL periphery are switched at the same time, an interference voltage is induced on the internal VCC network of the ASIC's because of the series inductance of the VCC supply pins. This interference is coupled to the outputs, the internal circuits and the reference voltage of the internal reference voltage generators, so that malfunctions may result. In order to avoid this inconvenient, the VCC supply voltage of the receiving converter circuits (1) is separated from the VCC supply voltage of the reference generator circuit (3). |
