Abstract
PURPOSE: To obtain an amplifying circuit for CTD which can easily be integrated with CTD and has an adequate DC component suppressing function, by utilizing the triode operation range of amplifying MOST.
CONSTITUTION: Once signal charge enters output diode 8 of CTDb, resetting MOST5 turns off. As the junction capacitor of output diode 8 is charged, gate G of amplifying MOST1 drops in potential to generate an input signal to amplifying circuit (a). When the input voltage is expressed by the ordinate and the output voltage by the abscissa, the gradient showing the degree of amplification is shown by curve K. In region (c) of this curve K, MOST1 enters the triode operation region and while the gate mutual conductance does not increase much, the degree of amplification decreases suddenly. For this porpose, the amplitude of a signal voltage energizing the gate terminal of MOST1 is set a little bit beyond region (c), so that a DC component based upon the background light of the input signal can greatly by suppressed.
