Spectrometer electronics chip architecture and measurements. (A) Free-induction decay (FID) experiments with ethylbenzene demonstrate multiphase generation; 32 FID signals excited by π/2 pulses with 32 different RF phases (Upper) are aligned (Lower), after shifting each signal by its respective excitation phase. These particular experiments were done before the magnet shimming. (B) Receiver input referred noise; and (C) receiver gain.
