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.

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： An imaging apparatus includes a solid-state imaging device that outputs a captured image signal in current mode, which in turn is subjected to CDS processing in current mode by a current signal detector, thus suppressing FPN noise. A captured image signal output by the current signal detector is amplified by a programmable gain amplifier to a certain level, and the amplified signal is converted by a current-to-voltage transducer into a voltage signal. In a clamp circuit including a current-output differential amplifier and a current adder, the differential amplifier compares the voltage signal with a reference voltage from a reference voltage source and feeds back a clamp current to the current adder so that the difference between the voltage signal and the reference voltage becomes substantially zero. The current adder is required to simply add a signal current and the clamp current.

摘要： A column analog-to-digital converter having a voltage comparator and a counter is arranged for each a vertical signal line. The voltage comparator compares a pixel signal inputted via the vertical signal line at each row control signal line with a reference voltage, thereby generating a pulse signal having a length in time axis corresponding to the magnitude of a reset component and a signal component. The counter counts a clock to measure the width of the pulse signal until the end of the comparison operation of the comparator, and stores a count at the end of the comparison. A communication and timing controller controls the voltage comparator and the counter so that, in a first process, the voltage comparator performs a comparison operation on a reset component with the counter performing a down-counting operation, and so that, in a second process, the voltage controller performs the comparison operation on a signal component with the counter performing an up-counting operation.

摘要： An asynchronous counter that is capable of switching count mode includes flip-flops, and three-input single-output tri-value switches respectively provided between the adjacent pairs of the flip-flops. The tri-value switches switch among three values, namely, non-inverting outputs and inverting outputs of the flip-flops and a power supply level. Each of the tri-value switches switch among the three input signals according to two-bit control signals, and input a selected signal to a clock terminal of a subsequent flip-flop. When count mode is switched according to the control signals, a count value immediately before the mode switching is set as an initial value, and counting after the mode switching is started from the initial value.
