A single-chip array of NMR receivers.
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 ohm 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 microm, resulting in a total active area of 1 mm by 2 mm for the array. The (1)H time-domain spin sensitivity of a single channel is approximately 1x10(15) spins/square root(Hz).
