Clock generator
A clock generator is provided, capable of automatically adjusting an output clock when process, voltage, or temperature variation occurs. The clock generator includes a current generator, for generating a first current and a second current according to a bias signal, an oscillator, coupled to the current generator, for generating a clock signal according to the first current, a frequency detector, coupled to the oscillator, for generating a control signal according to the clock signal and a reference signal, and a bias voltage adjuster, coupled to the current generator and the frequency detector, for adjusting the bias signal according to the control signal. When the signal frequency of the clock signal changes, the bias signal corresponds to the bias voltage adjuster, to adjust the first current and the second current.
