Özet

This paper presents an attractive and a new voltage-mode quadrature oscillator using a single Fully Balanced-Voltage Differencing Buffer Amplifier (FB-VDBA) as the active element. The circuit structure is very simple, consisting of merely one FB-VDBA, one resistor and two capacitors. The circuit is implemented using the commonly available OPA860 which results in low output impedance and high current drive capability. The proposed circuit also has a suitable architecture for IC production. Experimental results which are matched well with the theoretical assumptions are given.
