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.
