Integrated active tracking detector for MRI-guided interventions

Giovanni Boero, Jens Anders, Paul Sangiorgio

We present a fully integrated detector suitable for active tracking of interventional devices in MR-guided interventions. The single-chip microsystem consists of a detection coil, a tuning capacitor, an intermediate frequency downconversion receiver, and a ...

A fully integrated IQ-receiver for NMR microscopy

Giovanni Boero, Jens Anders, Paul Sangiorgio

We present a fully integrated CMOS receiver for micro-magnetic resonance imaging together with a custom-made micro-gradient system. The receiver is designed for an operating frequency of 300 MHz. The chip consists of an on-chip detection coil and tuning ca ...

A single-chip array of NMR receivers

Giovanni Boero, Jens Anders, Paul Sangiorgio

We present the first single-chip array of integrated NMR receivers for parallel spectroscopy and imaging. The array, optimized for operation at 300 MHz, is composed of eight separate channels, with each channel consisting of a detection coil, a tuning capa ...

An Integrated CMOS Receiver Chip for NMR-Applications

Giovanni Boero, Jens Anders, Paul Sangiorgio

We present the first CMOS-only receiver chip for NMR-applications at 300 MHz. The system consists of an on-chip reception coil, a tuning-capacitor, a downconversion-mixer and a low-frequency gain-stage as well as biasing and offset-compensation circuitry. ...

Anomalous double peak structure in superconductor/ferromagnet tunneling density of states

Paul Sangiorgio

We have experimentally investigated the density of states (DOS) in Nb/Ni (S/F) bilayers as a function of Ni thickness, d(F). Our thinnest samples show the usual DOS peak at +/-Delta(0), whereas intermediate-thickness samples have an anomalous "double-peak" ...
