Abstract
An integrated spectral-scanning nuclear magnetic
resonance imaging (MRI) transceiver is implemented in a 0.12
m
SiGe BiCMOS process. The MRI transmitter and receiver
circuitry is designed specifically for small-scale surface MRI
diagnostics applications where creating low (below 1 T) and
inhomogeneous magnetic field is more practical. The operation
frequency for magnetic resonance detection and analysis is tunable
from 1 kHz to 37 MHz, corresponding to 0–0.9 T magnetization
for
/49H (Hydrogen). T
