Patent ID: 8072522

Claim:
A solid-state imaging device comprising: a pixel unit in which unit pixels are arrayed; a complementary-signal generating unit that generates two kinds of complementary signals having complementarity with each other on the basis of analog pixel signals read out from the respective unit pixels in the pixel unit; two kinds of complementary signal lines on which the two kinds of complementary signals are transmitted; a horizontal scanning unit that transfers each of the two kinds of complementary signals on the complementary signal lines; a differential amplifying unit that receives the signals on the two kinds of complementary signal lines with differential inputs and compares the signals; and a complementary-signal amplifying unit that amplifies the respective signals on the two kinds of complementary signal lines, wherein, the differential amplifying unit receives the respective signals amplified by the complementary-signal amplifying unit with differential inputs and compares the signals, and the complementary-signal amplifying unit has a feedback circuit that acts in a direction for controlling amplitudes of the signals on the complementary signal lines on the basis of the amplified signals.
