Short summary
We have presented a CMOS-based NMR platform featuring arbitrary phase control and coherent detection in a non-zero intermediate frequency (IF) receiver architecture as well as active automatic temperature compensation. The proposed platform is centered around a custom-designed NMR-on-a-chip transceiver. The entire system achieves a phase stability well below 1° in consecutive pulse acquire experiments and keeps a normalized standard deviation in the measured T2 values of 0.45 % over 100 min.
