COMPLESSO PER L'ALIMENTAZIONE DI CORRENTE DI UN CIRCUITO LOGICO DI INIEZIONE.

摘要

In a combination of an integrated injection logic circuit (T1, T2, T10) and a current source circuit (V) connected to the injectors of the logic circuit for energising them, the collector currents and hence the speeds of the logic circuit inverter transistors are standardised from batch to batch of such combinations by comparing the collector current (ICT2) of an otherwise non- controlled transistor (T2) of the integrated circuit, which transistor is itself provided with a current injector (T1), with the output current (Iref) of a reference current source and controlling the output current of the current source circuit (V) in such manner as to reduce any deviation of the difference from a predetermined value to zero.
