摘要：

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.
