Abstract
In this paper a novel architecture for an integrated NMR receiver front-end for surgical guidance applications is described. While the chip consumes only 9 mA supply current from a 3.3 V power supply it has a measured input referred noise density of 0.7 nV/√Hz. The receiver consists of the reception coil, an on-chip tuning capacitor an LNA and a 50Ω output buffer. The system is designedfor operation in a B0-field of 1.5 T corresponding to a frequency of 63MHz. It is implemented in a 0.35 μm CMOS high voltage process and occupies a chip area of 500 μm x 760 μm.
