Abstract :
The Voltage controlled oscillators (VCO) are the useful and important component in data communication systems and must needed in applications like a modulation, demodulation and clock generator circuits. This paper focused on design of different voltage control oscillator (VCO) topology as basic, output switching, power switching, current mirror and symmetrical load with stability of oscillation frequency is improved 42% in case of output switching topology and stability of oscillation frequency has nearly ideal characteristics in case of supply voltage variation for current mirror topology with 10% variation in supply voltage.
