Metrology Laboratory (LAMLab)

The laboratory is focused on time and frequency metrology, electrical impedance metrology and noise metrology. The activities mainly deal with the development of phase noise measurements in oscillators, uncertainty analysis in atomic frequency standard, design of digital impedance bridges as well as the design of impedance standards, analysis of the uncertainty in impedance measurements, modelling of quantum Hall effect systems and low current measurements.

Keywords: frequency metrology, electrical metrology, low noise measurements, quantum Hall effects
