采用64通道CMOS CMOS阵列SMA 2SH- 64 A，对其信噪比进行了研究。单通道噪声基本上受到基线偏移的污染，这对所有相邻通道都是常见的。减去共同的基线偏移，我们发现，噪声水平降低到可以接受的设计参数，以及为实际使用。
Employing a 64-channel CMOS preamplifier array, SMA2SH - 64 A, we studied its signal-to-noise ratio. Single-channel noise was substantially contaminated with a base-line shift, which was common for all neighboring channels. Subtracting the common base-line shift, we found that the noise level decreased to be acceptable in terms of the design parameters as well as for practical use.
