Single chip dynamic nuclear polarization microsystem

Giovanni Boero, Gabriele Gualco, Alessandro Valentino Matheoud, Marco Grisi, Nergiz Sahin Solmaz

Integration of the sensitivity-relevant electronics of nuclear magnetic resonance (NMR) and electron spin resonance (ESR) spectrometers on a single chip is a promising approach to improve the limit of detection, especially for samples in the nanoliter and ...

Single-chip electron spin resonance detectors operating at 50 GHz, 92 GHz, and 146 GHz

Giovanni Boero, Jürgen Brugger, Jens Anders, Henrik Moodysson Rønnow, Ivica Zivkovic, Gabriele Gualco, Alessandro Valentino Matheoud

We report on the design and characterization of single-chip electron spin resonance (ESR) detectors operating at 50 GHz, 92 GHz, and 146 GHz. The core of the single-chip ESR detectors is an integrated LC-oscillator, formed by a single turn aluminum planar ...

A broadband single-chip transceiver for multi-nuclear NMR probes

Giovanni Boero, Gabriele Gualco, Marco Grisi

In this article, we present an integrated broadband complementary metal-oxide semiconductor single-chip transceiver suitable for the realization of multi-nuclear pulsed nuclear magnetic resonance (NMR) probes. The realized single-chip transceiver can be in ...

Cryogenic single chip electron spin resonance detectors

Gabriele Gualco

Methods based on the electron spin resonance (ESR) phenomenon are used to study paramagnetic systems at temperatures that ranges from 1000 to below 1 K. Commercially available spectrometers achieve spin sensitivities in the order of 10^(10) spins/¿Hz at ro ...

Frequency jumps in single chip microwave LC oscillators

Giovanni Boero, Gabriele Gualco, Marco Grisi

We report on the experimental observation of oscillation frequency jumps in microwave LC oscillators fabricated using standard complementary metal-oxide-semiconductor technologies. The LC oscillators, operating at a frequency of about 20 GHz, consist of a ...

Cryogenic single-chip electron spin resonance detector

Stefano Alberti, László Forró, Andrzej Sienkiewicz, Giovanni Boero, Jens Anders, Gabriele Gualco

We report on the design and characterization of a single-chip electron spin resonance detector, operating at a frequency of about 20 GHz and in a temperature range extending at least from 300 K down to 4 K. The detector consists of an LC oscillator formed ...

Room temperature strong coupling between a microwave oscillator and an ensemble of electron spins

Giovanni Boero, Jürgen Brugger, Jens Anders, Radoslaw Lisowski, Gabriele Gualco, David Michael Suter

We demonstrate theoretically and experimentally the possibility to achieve the strong coupling regime at room temperature with a microwave electronic oscillator coupled with an ensemble of electron spins. The coupled system shows bistable behaviour, with a ...
