Abstract :
The Letter introduces a new, extremely simple, sinusoidal oscillator based on opamp compensation poles. The circuit employs only four components, two internally compensated opamps, one resistor and a grounded capacitor, and can generate sinusoidal oscillations of frequencies up to the gain bandwidth product of the opamps. with modification(s), using an additional opamp or two analogue multipliers, the circuit can be readily converted into a VCO. Experimental results and SPICE simulations have confirmed the workability of the various modes of operation of the proposed configuration.
