Title:
CHARGE TRANSFER DEVICE
Document Type and Number:
Japanese Patent JPH01107573
Kind Code:
A
Abstract:

PURPOSE: To obtain a highly reliable charge transfer device, from which a large output signal can be taken out even if the amount of first charge is minute, by generating second charge having the large amount of charge based on the first charge, which is outputted from a charge coupled device, and taking out the output signal based on the charge.

CONSTITUTION: Second charge, whose amount of charge is larger than the amount of first charge, which is outputted from a charge coupled device, is supplied otherwise and stored. Thereafter the second charge is transferred. The amount of charge of the transferred second charge is amplified, and the output signal is taken out. Since the output voltage is taken out based on the amount of the second charge, which is larger than the amount of the first charge, in this way, the large output signal is secured even if the amount of the first charge is minute. Thus, a highly reliable charge transfer device, in which the charge outputted from the charge coupled device is amplified on the same substrate for the charge coupled device and can be outputted, can be obtained.
