Abstract
A clock generator capable of providing reduced low-frequency jitter clock signals without utilization of a crystal oscillator is introduced. The present invention clock generator utilizes a diode in related biasing circuit such that the generated control current to a current control oscillator is stable and clear due to the low flicker noise and low thermal noise of the voltage across the diode. The cost of PLL systems utilizing the present invention clock generator instead of a crystal oscillator is decreased. The adopted biasing circuit is introduced as well.
