This research present the method for generate sinusoidal signal with WeinBridge Oscillator circuit. This method used the mathematic analysis for determining the operation of the oscillator circuit. The natural response was second order differential equation. The circuit design begins from simulation with PSpice. When experimental result followed to theory Hardware Circuit was constructed. Analytical theory was confirmed by experimental result well agree.
