Differential transconductor stage dynamically controlled by the input signal's amplitude |
摘要 |
The dynamic range of operation of a differential transconductance input stage is reduced when the amplitude of the input signal decreases, thus reducing the level of the noise that is generated by the input stage. A DC signal representative of the sensed amplitude of the input signal is employed for either reducing the value of a common, emitter-degenerating resistance or of the bias current that is forced in the two branches of the differential input stage.
