A configurable matrix receiver comprises a plurality of antennas that
detect one or more signals. The antennas are coupled to a configurable
matrix comprising a plurality of amplifiers, one or more switches that
selectively couple the amplifiers in series fashion, and one or more
analog-to-digital converters (ADCs) that convert the output signals
generated by the amplifiers to digital form. For example, in one
embodiment, a matrix comprises a first amplifier having a first input and
a first output, and a second amplifier having a second input and a second
output, a switch to couple the first output of the first amplifier to a
the second input of the second amplifier, a first ADC coupled to the
first output of the first amplifier, and a second ADC coupled to the
second output of the second amplifier. In one embodiment, the signals
detected by the antennas include magnetic resonance (MR) signals.
