Abstract

<p>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 2.7×2.7µm<sup>2</sup> and a pixel size was 7×7µm<sup>2</sup>. By the results of meausrement, FPN(fixed pattern noise) in the reproduced image sampled at 3.2µs was suppressed to 1.27mV<sub>rms</sub>.</p>
