A voltage controlled oscillator (VCO) has an LC tank for generating a sinusoidal wave. The VCO uses a positive feedback circuit electrically connected to the LC tank for amplifying the sinusoidal wave. In addition, the VCO includes a noise reducing circuit having a T-shaped resistor configuration connected to the positive feedback circuit. The use of the T-shaped resistor configuration allows the VCO to reduce phase noise generated by the LC tank, and provide a high SNR. |
