Abstract
A voltage-controlled oscillator includes a voltage regulator, and a delay unit. The voltage regulator independently receives a first oscillation control signal and a second oscillation control signal to provide a regulated voltage signal which is represented by a regular ratio of combination of the first and second oscillation control signals, and the regulated voltage signal is feedback to the voltage regulator. The delay unit generates an output signal having a frequency varying in response to the regulated voltage signal.
