MOS-type solid-state imaging apparatus
An MOS-type solid-state imaging apparatus includes an imaging region formed by two-dimensionally arranging unit cells serving as photoelectric conversion portions on a semiconductor substrate, a plurality of vertical address lines arranged in a row direction of the imaging region to select a row of unit cells to be addressed, a plurality of vertical signal lines arranged in a column direction of the imaging region to read out signals from the unit cells in each column, a plurality of load transistors each connected to one end of each of the vertical signal lines, and a plurality of horizontal selection transistors each connected to the other end of each of the vertical signal lines. In this apparatus, each unit cell includes a photodiode serving as a photoelectric conversion portion, an amplification transistor having a gate to which an output from the photodiode is supplied, and a source and a drain respectively connected to the vertical signal line and the vertical address line, an address capacitor connected between the gate of the amplification transistor and the vertical address line, and a reset transistor connected in parallel with the address capacitor.
