ABSTRACT:
An electronic circuit including an amplifier having an input adapted for coupling to an analog signal source; a current source coupled to the output of the amplifier; a feedback transistor having a collector electrode and emitter electrode connected in series between the output of the current source and the input of the amplifier; and a lead network, including a capacitor connected between the input and output of the amplifier, for stabilizing the electronic circuit. With such arrangement the current in the collector electrode of the feedback transistor rapidly becomes related to current fed to the input of the amplifier by the analog signal source.
