Abstract

A gyrator is a non-reciprocal circuit element which, in ideal form, is a lossless four terminal coupling element with the skew symmetric open circuit impedance matrix (Image Omitted) where gamma is purely resistive and is called the gyration resistance. Such devices are described in "The Gyrator as a Circuit Element", S. Tehon, Proc. Symposium on Circuit Analysis, 1955, University of Illinois.

where gamma is purely resistive and is called the gyration resistance. Such devices are described in "The Gyrator as a Circuit Element", S. Tehon, Proc. Symposium on Circuit Analysis, 1955, University of Illinois.

This realization of a gyrator having input terminals 1 and output terminals 2 utilizes a negative impedance converter 3 having first and second loads 4 and 5. The four terminal network comprised of NIC 3 and resistive loads 4 and 5 has a nonreciprocal open circuit impedance matrix Z:
