我们提出了第一个单芯片阵列的集成NMR接收器的并行光谱和成像。该阵列针对300 MHz工作频率进行了优化，由8个独立通道组成，每个通道由检测线圈、调谐电容器、低噪声放大器和50 Ω缓冲器组成。由于所有的集成电子设备都放置在接收线圈下面，因此阵列被密集地包装。每个单通道接收线圈的直径为500 μ m，导致阵列的总有效面积为1 mm × 2 mm。单通道的H-1时域自旋灵敏度约为1 × 10（15）自旋/根Hz。(C)2009 Elsevier Inc. All rights reserved.
We present the first single-chip array of integrated NMR receivers for parallel spectroscopy and imaging. The array, optimized for operation at 300 MHz, is composed of eight separate channels, with each channel consisting of a detection coil, a tuning capacitor, a low noise amplifier and a 50 Omega buffer. As all the integrated electronics are placed underneath the reception coils, the array is densely packed. Each single-channel reception coil has a diameter of 500 mu m, resulting in a total active area of 1 mm by 2 mm for the array. The H-1 time-domain spin sensitivity of a single channel is approximately 1 X 10(15) spins/root Hz. (C) 2009 Elsevier Inc. All rights reserved.
