ABSTRACT:
A resistor inserted between the collector of a common emitter transistor in a cascode amplifier and the emitter of the ensuing common base-amplifier transistor in conjunction with an operational amplifier responds to the collector current of the common emitter transistor to develop a degenerative-feedback-voltage signal for application to its emitter-base circuit.
