Abstract
The present invention relates to the improvement of a phase noise characteristics of supply voltage in VCO. The delay in delay cells may be controlled to use the resistor of a transmission gate instead of a tail current. That is, the delay of cells is controlled by applying the overdrive voltage in transmission gate. And the self-regulating may be possible to composing a feedback inside the delay cells.
