Abstract
An integrated spectral-scanning magnetic
resonance imaging (MRI) technique is implemented in a
0.12μm SiGe BiCMOS process. This system is designed for
small-scale MRI applications with non-uniform and low
magnetic fields. The system is capable of generating
customized magnetic resonance (MR) excitation signals, and
also recovering the MR response using a coherent direct
conversion receiver. The operation frequency is tunable from
DC to 37MHz for wide-band MRI and up to 250MHz for
narrow-band MR spectroscopy
