چکیده
In this paper, a Single resistance controlled Sinusoidal Oscillators is presented using a single current feedback operational amplifier (CFOA). The main feature of this circuit configuration is that frequency of oscillation (FO) and condition of oscillation (CO) can be controlled by single resistance. It uses single CFOA and minimum passive components that are three voltage controlled resistors and one capacitor only to realize oscillator response. The circuit topology is verified by simulating the circuit on PSPICE using TSMC 0.35μm CMOS Technology process parameters with supply voltages of +/1.25V and controlling voltage Vb1=0.35V, Vb2= -0.55V. The simulated and theoretical results were found to be in good agreement with each other.

Abstract Although a large number of single current feedback op-amp (CFOA)-based sinusoidal oscillator circuits have been proposed in the literature, to the best knowledge of the authors, no single-CFOA oscillator configuration has been reported earlier which can absorb all the parasitic impedances of the CFOA in the various external passive elements employed. The major intention of this paper i...
