Abstract
PURPOSE: To reduce the feed-through as well as the reset noise, by approximating the reset pulse voltage at the non-conducting time of the reset transistor to the fixed reset gate potential when the necessary maximum charge amount is stored to the floating diffusion layer.
CONSTITUTION: The potential is set to level 23 when the necessary maximum charge amount is stored to floating diffusion layer 17. In that case, the charge does not flow out toward reset drain 18 until the charge detection amount is secured if the channel potential right under reset gate 19 is shallower than level 23. Thus the normal charge detection is carried out. On the other hand, the voltage of reset pulse 25 at the non-conducting time of the reset transistor is approximated to the gate voltage with which the coincidence is obtained between the potential of layer 17 when the necessary maximum charge amount is stored to layer 17 and the channel potential right under noise 27 can be reduced.
