ABSTRACT:
A charge transfer device comprises a charge transfer section having a charge transfer region formed in a semiconductor substrate and transfer electrodes formed on the semiconductor substrate, and a reset transistor having a floating diffusion region formed in the semiconductor substrate for receiving an electric charge transferred from the charge transfer section, a reset drain applied with a reset voltage, and a reset gate formed above a channel between the floating diffusion region and the reset drain, the reset gate being applied with a reset pulse. A a peak hold circuit is connected to the reset gate of the reset transistor for hold a peak level of the reset voltage. A potential detection circuit includes a dummy transistor having a drain connected to a voltage V.sub.DD, a source grounded through a resistor which is considerably larger than an on-resistance of the dummy transistor itself, and a gate electrode connected to an output of the peak hold circuit. The dummy transistor has the same characteristics as that of the reset transistor, and the drain of the dummy transistor is directly connected to the reset drain of the reset transistor.
