charge-detection node and output amplifier
The buffer amplifier converts the charge into a video signal. Figure 4 shows the circuit diagram of the
charge-detection node and output amplifier. As charge is transferred into the detection node, the potential of
this node changes in proportion to the amount of signal received. This change is sensed by a MOS transistor
and, after proper buffering, the signal is supplied to the output terminal of the image sensor. After the potential
change is sensed, the node is reset to a reference voltage supplied by an on-chip reference generator. The reset
is accomplished by a reset gate that is connected internally to the serial register. The detection node and buffer
amplifier are located a short distance away from the edge of the storage area; therefore, two dummy cells are
used to span this distance.
