| Abstract | ||
| The oscillator is a form of frequency generators which can be generate a sinusoidal wave with constant frequency and amplitude. The frequency oscillator can be considered as a one of basic circuits, which must be existing in most electrical, electronic, communication circuits and systems. In this paper, a proposed design of sine wave oscillator type RC phase shift has been performed using three approaches. The first approach proposed design is done theoretically using the basic theorems used to generate oscillations, such as the condition of oscillation criteria. Secondly it is done using simulation technique (multisim11). Thirdly the simulated design is implemented practically using single operational amplifier with passive elements such as resistors & capacitors. All the obtained results from the above three approaches (3.800 kHz, 3.510 kHz & 3.600 kHz respectively) are seems to be equal approximately. These obtained results from the designed oscillator were very encouraging. | ||
