Third–order nulling effect in Darlington transistors

Third–order nulling effect in Darlington transistors
Third–order nulling effect in Darlington transistors
In this paper we present the first proof that a Darlington transistor has an inherent nulling effect in its third-order intermodulation distortion, similar to the well known third-order null seen in single BJT amplifiers. It is proven mathematically and by measurement. The results suggest the null actually becomes feasible as a source of distortion reduction in a Darlington BJT amplifier.

Abstract

In this paper we present the first proof that a Darlington transistor has an inherent nulling effect in its third-order intermodulation distortion, similar to the well known third-order null seen in single BJT amplifiers. It is proven mathematically and by measurement. The results suggest the null actually becomes feasible as a source of distortion reduction in a Darlington BJT amplifier.
