LINE TRANSFER PHOTOSENSITIVE DEVICE WITH FEED-BACK AMPLIFIERS |
摘要 |
Use is made of a row memory and a read register, in which charge transfer takes place in volume. The threshold voltage of the negative feedback amplifiers is adjusted so that the operating point of the assembly constituted by each amplifier, the diode and the gate of the memory to which it is connected is located in the high gain zone of the transfer characteristic of the amplifier. It is possible to adjust the threshold voltage by an enhancement in its own type of impurities of the zone of the substrate located beneath the gate of one of the MOS transistors constituting the amplifier. |
