Hybrid integrated gyrator in dual-in-line package for universal application

The properties of a thick-film hybrid gyrator are shown by experimental results and are verified by calculation. The relatively small size of this gyrator is due to a transistor circuit without resistors. Two resistors determining the gyration constants have to be connected externally. Dynamic range, dc power consumption, and enhancement can be adjusted by one or two further resistors. Those features give the user great design flexibility and show the way for future monolithic integration. Lowfrequency without enhancement is 100 and more, power consumption is as low as 5 mW, and the frequency range is up to 100 kHz.
