A sinusoidal oscillator using a single commercially available IC with gain control of the oscillation frequency is proposed in this paper. The proposed sinusoidal oscillator has a single commercially available IC, three resistors and two grounded capacitors. The LT1228, available from Linear Technology Corporation, has been used in this circuit. The oscillation condition is configured by the transconductance gain and the values of the resistors. Also, the oscillation frequency is freely adjusted by the gain of a voltage amplifier without affecting the oscillation condition. The theoretical analysis is verified by the satisfactory experimental results.
