Title:
ELECTRIC CIRCUIT AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/029644
Kind Code:
A1
Abstract:
In an electric circuit including a plurality of circuit blocks that operate with different clocks, a noise generated by a first circuit that operates with a first clock at an output of a second circuit that operates with a second clock whose frequency is different from that of the first clock is reduced. For this object, the electric circuit comprises a synchronization detection circuit for detecting synchronization between the first clock and the second clock, a storage circuit for storing an output noise pattern of the second circuit according to the synchronization detection of the synchronization detection circuit, and a correction circuit. The correction circuit corrects the output of the second circuit by using the output noise pattern.
