Binary signal generator amplitude stabiliser - has current compensator and is esp. for differential amplifier output stages supplying discontinuous loads

摘要

The amplitude stabilisation circuit is for binary signal generators where the load impedance may be discontinuous and variable. The circuit is esp. applicable to the output stage of a differential amplifier used for signal switching. The stabiliser is fed from a constant current source (13') in series with a current compensation generator (10) having an amplifying stage (11) to which the input signal line (e1) is brought. The compensation stage provides an output (Io) as a function of its input (Ii) to an output stage (12) supplied from the constant current source and controlled by a second input signal (e2). The stabiliser output is fed by a bus across the load (14).
