Abstract

The generation of sine wave at low frequency is very tedious because the size of the inductors used in the circuit is very large and bulky. Hence the inductor is replaced with the simulated inductor. This study deals with the generation of sine wave from an active tuned oscillator which consists of the simulated inductor and capacitor. The oscillator makes use of the basic blocks of a band pass filter using the simulated inductor and a diode limiter. This circuit has the advantage of improving the quality of the wave by increasing the Q-factor of the band pass filter. It also decreases the Total Harmonic Distortion (THD) in the sine wave. The simulation is done using the analog simulator software PSPICE and the total harmonic distortion is calculated using MATLAB.
