Title:
画素読み出しスイッチ・コンデンサ・バッファ回路およびその方法
Document Type and Number:
Japanese Patent JP4867028
Kind Code:
B2
Abstract:
A pixel signal amplification circuit (200) receives a signal from a pixel element. A first semiconductor switch (225a) is connected to the pixel element and transfers a reset value of the pixel signal to a first storage capacitor (C1). A second semiconductor switch (235a) is also connected to the pixel element and transfers a sampled pixel signal to a second storage capacitor (C3). A differential voltage amplifier (OP1) generates an amplified signal of the difference between the values stored on the first and second storage capacitors (C1 and C3).
