Design Wien Bridge Oscillator for VLF to VHF Using Practical Op – Amp

An electronic oscillator is generally a major part of electrical, electronic and communications circuits and systems and it is can be divided into linear and nonlinear families. Wien Bridge is a type of RC phase shift oscillators mostly used for around 1MHz and its design adopts positive feedback technology. In this research, novel look the reasons for the inability to achieve high frequencies was understanding and the ambiguity was removing from the determinants of obtaining a high frequency signal for this type of oscillators, also, new results were obtained with a unique presentation. The output formula for the oscillation resonant frequency was deriving based on the oscillator’s theory. The design has beaning successfully achieved by using a practical high-performance op-amp and from the simulation results the frequency bandwidth was 50.7211 MHZ from,VLF (9.83 HZ ) to VHF (50.73 MHZ) and. These unique and interesting scientific findings were encouraging.
