Abstract
A charge-coupled amplifier having a transistor used for transferring an electric charge between capacitors is provided with a charging means for charging the capacitor connected to an emitter of the transistor at a level of a sample-held signal voltage, and a differential signal voltage between the sample-held signal voltage and another sample-held signal voltage applied to a base is derived from a collector of the transistor with a delay of one sampling interval. So that, the charge-coupled amplifier has faculties of a differential amplifier and an analog shift register. Accordingly, a serial-parallel type A-D converting device having a high exactness can be formed simply by using the charge-coupled amplifier.
