Abstract
PURPOSE: To increase the signal detection sensitivity at the output step by removing part of the DC component among the signal charge and thus reducing the increment of the transfer electrode area which is caused by the increment of the delay step number.
CONSTITUTION: Among the signal charge stored at time t1 under delay charge transfer electrode 40 composed of the charge coupling element and the like, the charge which can get over the channel potential barrier under electrode 41 to which voltage Vref is applied at time t2 is transferred under electrode 44. And the rest charge stays under electrode 40. In this case, if voltage Vref is set previously so that the charge which can get over the potential barrier may correspond to the AC component of the signal, only the AC part is transferred. And the gate of electrode 42 is opened at time t2 to throw away the charge corresponding to the DC part from drain 43, thus completing one cycle. As a result, the increment is reduced for the transfer electrode area, thus increasing the signal detection sensitivity at the output step.
