Abstract
A new technique for providing stable, high quality factor Y-gyrators over a wide frequency range is presented. A compensating phase shift that tracks the gyrator´s parasitic phase shift is adopted using voltage variable capacitors. The technique has been implemented in an ordinary semi-floating gyrator circuit where the useable frequency range was extended from 60 kHz to 220 kHz. Further, the low frequency Q-factor has been seen to be enchanged
