Streszczenie

This article introduces novel current-mode quadrature oscillator circuit based on DO-CCCFTA and three grounded passive components. The oscillator circuit can be generated four-phase sinusoidal current signal. The oscillation condition (OC) can be non-interactively controlled from oscillation frequency (OF). Furthermore, its high impedance in outputs can directly connect in current-mode circuit and used only grounded passive components that are very suitable to future fabrication into integrated circuit. The PSPICE simulations and experimental method were implemented to theoretically analyze the proposed oscillator.

Abstract
