Abstract:
1. An image sensing apparatus comprising: a pixel array in which a plurality of pixels are arrayed so as to form rows and columns; a readout unit, which reads out a signal from the pixel array; a first terminal, which receives a first power supply voltage; a second terminal, which receives a second power supply voltage; and a differential processing circuit, wherein the readout unit includes: wherein each column amplifier includes a first input transistor having a gate electrode and back-gate electrode, the gate electrode receiving a signal from a pixel of the pixel array, and the back-gate electrode being connected to the first power supply line, wherein each holding unit includes first and second capacitors each having a first electrode and a second electrode, the first electrodes of the first and second capacitors receiving signals amplified by a corresponding column amplifier, and the second electrodes of the first and second capacitors being connected to the second power supply line, and wherein the differential processing circuit performs a differential processing on a signal held by the first capacitor and a signal held by the second capacitor.
