Abstract
PURPOSE: To enable perfect circuit integration for AD converter, by enabling the high speed AD conversion up to the frequency of a half the clock frequency theoretically, through the use of CCD.
CONSTITUTION: The charge corresponding to the analog signal inputted from the terminal 120 of CCD 101 is transferred from left to right in the charge storage sections 102 to 110 with the two phase drive pulse fed to the terminals 126 and 127. One end of the charge storage section is provided with the discharge storage section 202 measuring a given amount of the transferred charge, detecting section 203 detecting the measured charge, and control gate 201 controlling the charge amount measured. The size of the charge storage section 202 determines the charge amount measured and the area of the gate electrode 201 is set so that it is the same for each storage section. Next, charge is fed to the code conversion circuit 220 with the delay circuits 204 to 211 connected to the detector 203 and set for the delay time shorter by one bit, and it is picked up as digital code from the terminals 221 to 223.
