Measurement Data for Paper "Characterisation of an EMI-Improved Integrated Folded Cascode Amplifier Structure Using the EMIRR Measurement Method"

This dataset is associated to the paper "Characterisation of an EMI-Improved Integrated Folded Cascode Amplifier Structure Using the EMIRR Measurement Method". In this paper, we analyse the robustness of OpAmps against EMI. Therefore we compare a nominal folded cascode amplifier with an EMI-improved amplifier by adding a second cross-coupled double differential input pair. We perform measurements on the manufactured test chip structures to determine nominal characteristics (gain, offset, GBWP and phase margin), as well as EMI-related characteristics (EMI-induced offset resp. EMIRR). Based on these characteristics, we compare both structures with regard to their performance. Further on, we put the measurements into relation with our previous findings that we obtained from simulation.

This dataset contains the following measurement data for five test chips, each containing two OpAmps:

• DC sweep (coarse and fine),
• AC sweep,
• Power consumption and
• EMI-Induced Offset for the non-inverting input pin.
