@article{Linvill1953TransistorNC, title={Transistor Negative-Impedance Converters}, author={John G. Linvill}, journal={Proceedings of the IRE}, year={1953}, volume={41}, pages={725-729} }

Negative impedances having very stable characteristics are obtained with circuits using transistors. The physical characteristics of transistors, compactness, long life, simple power requirements, plus constancy of pertinent electrical parameters enhance their practical utility in the production of negative impedances.
