DC OFFSET CANCELLATION CIRCUIT |
摘要 |
PURPOSE: A DC offset cancellation circuit is provided to regulate the amount of current from a feedback capacitor at a 2xn stage through a plurality of pulse signal. CONSTITUTION: Current is provided to a switching unit(130) through a feedback capacitor. An electric charge quantity adjusting unit(140) charges DC offset charge corresponding to the current. The electric charge quantity adjusting unit transfers the DC offset electric charge to a sampling capacitor through a rotation capacitor. Therefore, the sampling capacitor firstly stores the DC offset electric charge. Then, the sampling capacitor secondly stores electric charge corresponding to the input signal.
