    摘要: An image sensor with a small circuit area is provided. In the image sensor, a TX decoder which generates transfer signals TX includes a latch circuit. The latch circuit is set when a corresponding row group is selected and when a set signal is set to an “H” level, and is reset when a reset signal is set to an “L” level. The latch circuit serves also as a voltage level shift circuit which converts the “H” level of a signal from a first power supply voltage into a second power supply voltage. Therefore, plural row groups can be selected by setting plural latch circuits. It is not necessary to provide a voltage level shift circuit separately.

    摘要: There is provided a solid-state image pickup device including ADCs that can be arranged in a limited space. The potential of a pixel signal outputted through a vertical readout line is held at a node. A plurality of capacitors are capacitively coupled to the node at which the pixel signal is held. The potential of the node is decreased in a stepwise manner by sequentially switching the voltages of the counter electrodes of the capacitors by the control of transistors. A comparator compares the potential of the node with the potential of the dark state of the pixel, and determines the upper bits of a digital value when the potential of the node becomes lower than the potential of the dark state. Following this, the conversion of the lower bits of the digital value is started. Therefore, it is possible to simplify the configuration of each ADC and arrange each ADC in a limited space.

    摘要: A semiconductor integrated circuit device has a negative voltage generation circuit provided at each power supply circuit unit for six memory macros. Therefore, the response with respect to variation in a negative voltage is increased. In a standby mode, a negative voltage supply line for the six memory macros is connected by a switch circuit, and only a negative voltage generation circuit of one power supply circuit unit among six negative voltage generation circuits of the six power supply circuit units is rendered active. Thus, increase in standby current can be prevented.

Then, the amplifier part amplifies a signal of the data line pair on an amplifier data line pair to output the amplified signal as block data outputs at timing indicated by an amplifier enable signal and an amplifier control signal. Further, the eight stage data blocks are coupled with each other from the first stage to the last stage so that the preceding stage block data outputs may be provided to the following stage data line pair as block data inputs, respectively.
