摘要： The present disclosure relates to a solid state imaging device and an electronic device from which a holding unit for holding information in a pixel can be eliminated. When a charge distribution unit distributes a pixel signal SIG to a first ADC, a pixel signal representing only reflection light is divided for allocation. When the charge distribution unit distributes a pixel signal SIG to a second ADC, a pixel signal representing background light and reflection light (partial) is divided for allocation. When the charge distribution unit distributes a pixel signal SIG to a third ADC, a pixel signal representing background light and reflection light (the rest) is divided for allocation. During a period in which no signal is acquired, a discharge transistor functions as an overflow portion for releasing electrical charge. The present disclosure can be applied to, for example, a solid state imaging device used for an imaging device.

摘要： An imaging device for improving the determining speed of a comparator and reducing power consumption. The comparator imaging device includes a differential input circuit that operates with a first power supply voltage, the differential input circuit outputs a signal when an input signal is higher than a reference signal in voltage, and a positive feedback circuit that operates with a second power supply voltage lower than the first power supply voltage. The positive feedback circuit accelerates transition speed when a compared result signal indicating a compared result between the input signal and the reference signal in voltage, is inverted, on the basis of the output signal of the differential input circuit. The imaging device further includes a voltage conversion circuit that converts the output signal of the differential input circuit into a signal corresponding to the second power supply voltage.

摘要： The present technology relates to an imaging element, a driving method, and an electronic apparatus that can decrease a voltage and increase a saturation signal amount.In each pixel configuring a pixel array unit, a photodiode receiving light from a subject and performing photoelectric conversion on the light and a first charge accumulating unit accumulating charges generated by the photodiode are provided. A reset gate unit to initialize the first charge accumulating unit is connected to the first charge accumulating unit through a third transfer gate unit. When the first charge accumulating unit is initialized, a voltage is applied to gate electrodes of the third transfer gate unit and the reset gate unit and a positive voltage is applied to a well region provided with a pixel to assist voltage application. Thereby, initialization is appropriately performed and a reset level is suppressed low. As a result, a voltage can be decreased and a saturation signal amount can be increased. The present technology can be applied to a solid-state imaging element.
