2次元集積化磁気センサへの相関二重サンプリングの導入とノイズ低減に関する検討

抄録

A CDS (correlated double sampling) method was applied to two-dimensional magnetic sensors. The two-dimensional integrated magnetic sensor used for the consideration of CDS was composed of a 64×64 array of Hall sensors. The size of a Hall element was 2.7×2.7µm² and a pixel size was 7×7µm². By the results of meausrement, FPN(fixed pattern noise) in the reproduced image sampled at 3.2µs was suppressed to 1.27mV_rms.
