Abstract :
The goal of this research is to improve the performance of NMR microscopy systems by fabricating the RF detection microcoil and preamplifier on a single monolithic GaAs substrate. The planar microcoil consists of 4-7 turns of gold conductor. A simple impedance matching network links the microcoil to a single stage, common source configuration, GaAs MESFET preamplifier
