CLOCK GENERATOR

摘要

PURPOSE: A clock generation circuit is provided to guarantee a stable circuit operation. CONSTITUTION: A clock generation circuit comprises a noise detection unit (210) and a clock generation unit (220). The noise detection unit generates a noise detection signal by detecting noise included in a set of input information. An internal clock generation unit generates an internal clock signal which corresponds to the input signal and adjusts a bandwidth in response to the noise detection signal. The input information includes a power voltage or a clock signal inputted to the internal clock generation unit. [Reference numerals] (210) Noise detection unit; (220) Clock generation unit
