ABSTRACT:
The invention relates to a semiconductor device including a charge transfer device having an output stage (8). The output stage (8) has a read-out zone (9), a feedback capacitor (11) and an amplifier (10). An inverting input (15) of the amplifier (10) is connected to the read-out zone (9) and an output (16) of the amplifier (10) is fed back via the feedback capacitor (11) to the inverting input (15). According to the invention, the capacitor (11) is a capacitor of the MOS type and means are provided by which during operation of the charge transfer device the surface potential of a surface region (13) in the capacitor (11) is solely determined by the potential of the read-out zone (9). Consequently, the capacitance of the feedback capacitor (11) is dependent upon the potential across it, as a result of which there is a linear relation between the charge supplied to the read-out zone (9) and the voltage variation across the capacitor (11 ). Thus, this voltage variation is an accurate measure of the supplied charge.
