Abstract

PURPOSE: To eliminate the noise in case the clock of more than several MHz is used, by clamping with the fixed cycle each reference potential in the signal which is obtained by giving the sample holding to the output signal of CCD with the fixed cycle.
CONSTITUTION: Detecting diode 3 is provided under transfer electrode 2 of CCD1; and with transfer electrode 4 to which the 2-phase clock voltage of ϕ1 and ϕ2 is applied, the signal charge varies the potential of diode 3. This potential change is extracted in the form of output 6 via amplifier 5. In this case, the potential of diode 3 is reset to the reference potential with pulse 8 of the fixed cycle. For output 6 containing the noise, each reference potential and signal potential are sample-held 14 with every cycle by pulse 16 having the frequency double the clock frequency. And the output 17 is clamped 18 to the fixed potential in the pulse 20 which is equal to the clock frequency and less than 1/2 cycle of the clock.
