ABSTRACT:
Regenerating amplifier for use with two charge coupled devices comprising field effect transistors to pre-charge the output diffusion capacitance of an output charge coupled device and the input diffusion capacitance of an input charge coupled device. The output diffusion capacitance is discharged by the arrival of output charge, in turn holding off an input gate such that the charge on the input diffusion capacitance is not shifted into the input charge coupled device. Various embodiments having control potentials and a field effect transistor to fully discharge the input diffusion capacitance of an input charge coupled device being usable with a plurality of input charge coupled devices having corresponding output charge coupled devices wherein individual charging transistors are available to charge each output diffusion zone capacitance with a common transistor being used to charge all input diffusion capacitances.
