Abstract :
The development of an integrated detector consisting of a planar microcoil and low noise preamplifier for nuclear magnetic resonance (NMR) microscopy is described. The detector is designed to operate at 500 MHz (11.75 T). These customized detectors may be particularly important for NMR investigations of single cells, where it may become impractical to passively impedance match microcoils with extremely small values of impedance to 50 Ω or to electrically connect the microcoils to remotely located impedance matching and preamplifier circuitry
