The optical signal electric charge transferred to this analog shift register is successively transferred out and guided to the output region. • A buried type CCD that can be driven by a two phase clock (ø1, ø2) is used for the analog shift register. c) Output region • The signal charge that is transferred to the output region is sent to the detector where impedance transformation is done using two source follower stages. • The DC level component and the clock noise component not containing optical signals are output from the DS pin. • By carrying out differential amplification of the two outputs OS and DS externally, it is possible to obtain an output signal with a high S/N ratio by reducing the clock noise, etc. |
