Abstract
A noise removal circuit. The noise removal circuit comprises a crystal oscillator and a level decision module. The crystal oscillator generates an oscillating signal and an output clock signal. The level decision module detects the signal level of the oscillating signal and outputs the output clock signal when the signal level of the oscillating signal exceeds a first reference level.
