DESIGN & SIMULATION OF SINUSOIDAL OSCILLATOR USING 0.18 μm CMOS TECHNOLOGY OP-AMP

It introduces a new, extremely simple, sinusoidal oscillator based on op-amp compensation poles. The circuit employs only four components, two internally compensated op-amp, one resistor, one grounded capacitor. It can generate sinusoidal oscillations of frequencies up to the gain bandwidth product of the op-amps. With the help of some modifications using an additional op-amp or two analogue multipliers. This circuit can be converted into a VCO. The experimental results and SPICE simulations de(Op-Amp) have confirmed the work ability of the various modes of operation of the proposed configuration VCO (voltage controlled oscillator) by using 0.18 mu m CMOS Technology op-amp. It is a very simple circuit employs only four components, two internally compensated 0.18 mu m CMOS Technology op-amps, one resistor and a grounded capacitor. I used AWR (microwave office) software for implement this work.
