title = "A broadband transceiver ASIC for X-nuclei NMR spectroscopy in 0.13 μm BiCMOS",
abstract = "In this paper, we present a fully-integrated transceiver ASIC (NMR-on-a-chip) for multi-nuclei nuclear magnetic resonance (NMR) measurements with operating frequencies up to 770 MHz. The NMR-on-a-chip transceiver co-integrates a low-IF receiver, consisting of a low-noise amplifier, quadrature down-conversion mixers followed by intermediate-frequency variable gain amplifiers, a power amplifier, and a frequency generation block. The ASIC is realized in a 0.13 μm SiGe BiCMOS technology and occupies a total chip area of 1100×900 μm2. The power amplifier has a maximum peak-to-peak output current of ITX,pp = 210 mA. The receiver chain has a maximum conversion gain of ARX = 66 dB with a minimum input-referred noise of v_n,min = 610 pV Hz . The chip performance is also verified in the target NMR application, in which the presented system achieves a state-of-the-art normalized spin sensitivity of 8.3 × 1017spins Hz ˙ T2m. ",
