prof. Sam Ben-Yaakov in his video explains behaviour of ferroelectric dielectric ceramic materials such as BaTiO3 class 2 materials used in most common MLCC ceramic capacitors.
Outline:
- general specification of commercial ceramic capacitor
- ESR as a function of DC BIAS voltage
- piezoelectricity
- non-linear capacitor modelling
based on Vicor Seminar_November_2019
The thesis about the piezoelectric resonances, mentioned in this presentation, can be downloaded here.
