Charge transfer readout circuits

摘要: During readout, the signals induced on columns of a charge transfer array cause currents to flow through respective conduction paths field effect transistors connected columns. The threshold voltage V th each transistor is compensated for prior readout by establishing gate electrode thereof at quiescent bias level c +V , where source that transistor. effects dark current or other fixed signal it desired discriminate against associated with array, also may be reducing an amount proportional thereto.
