摘要： An NchMOS transistor Q71 on the input side of a current mirror 70 is made function as a voltage operating-point setting portion so that a pixel signal line potential (voltage of a horizontal signal line 20) would be constantly stable nearly at the GND. Then, an amplification factor and linearity become good in an amplification transistor in the solid imaging device 3. A current copier 90 is made function as a current sampling portion so as to receive a signal current IIN of the solid imaging device 3 through the current mirror 70 to carry out sampling of a pixel signal in a resetting period in the shape of current component as the pixel signal is. Calculating differential between a current component in a detecting period and an offset current, which is the current component in a resetting period in sampling, allows an offset component included in the pixel signal to be removed and only pure signal Isig to be picked up at an output terminal Iout, so that the FPN restraining function can be fulfilled.

摘要： In a charge-pump booster circuit, the control clock is controlled on a small-step basis to thereby suppress the boost amplitude and the occurrence of various noises. Provided are a charge-pump booster circuit section for boosting an external power voltage in absolute value level, a boost-voltage feedback section for controlling the booster circuit section, and a clock buffer section. In the boost-voltage feedback section, an output level of the booster circuit section is detected by a voltage detecting section. This is compared with a reference level, and depending upon the comparison result, a count operation is made in an up/down counter section. Based on the count value, the control amount is shifted on a small-step basis from the D/A converter section, thereby controlling the power voltage of the clock buffer section 300 through the level shifter section.
