Realization of a Magnetoresistive Gyrator Circuit

The realization of a gyrator network with the use of rnagnetoresistive devices is analyzed from the viewpoint of minimizing the required number of negative-resistance devices. It is demonstrated that the special nature of these devices, which permits their output polarities to be easily reversed, enables the gyrator network to be realized using only one negative-resistance element. The devices investigated herein are the cryotron operating in a linear mode and the conventional magnetoresistive device. The various methods of connecting the devices are compared, and considerations are given to the advantages and the disadvantages involved in the practical implementation of the various circuit arrangements.
