ABSTRACT:
A time-independent CCD charge amplifier comprises first and second CCD lines each having a plurality of electrode pairs disposed over a layer of silicon dioxide overlying a semiconductor substrate. Two clocks which are in a predetermined phase relationship with respect to one another are connected to alternate electrode pairs. The second CCD line further comprises a clocked-source charge injector, the input gate of which is electrically coupled to the signal source, which in a preferred embodiment comprises a surface potential tap in the first CCD line. According to a preferred embodiment, charge is non-destructively sampled from the first CCD line and is amplified by a predetermined factor in the second CCD line.
