  • Output following intermediate cascode circuit
    Patent number: 4511857
    Abstract: The input terminal (3) of a voltage-follower output stage (22) is isolated from its signal source (20, 21) by an output following intermediate cascode circuit (23) comprised of a transconductance amplifier which may take the form of a common-base transistor amplifier (Q.sub.24) with its emitter connected to a terminal (1) at the output of the signal source, its base connected to the output terminal (2) of the voltage follower output stage, and its collector connected to the input terminal (3) of the voltage-follower output stage. The output following intermediate cascode circuit (OFICC) isolates the voltage signal at the input terminal (3) of the voltage-follower output stage from the signal source so that nonlinearities in the output voltage of the voltage-follower output stage are not coupled back into the signal source.
