Application Note for
High EMC Performance OP-Amp and Comparator
The influence of EMI on Op-Amp and Comparator
How to measure EMIRR (EMI Rejection Ratio)
Including a smartphone and a cell-phone the electronic equipment with the wireless communication function spreads in late years. Therefore, it increases that electronic equipment is affected by the electric wave. Especially, the malfunction of the electronic circuit by electromagnetic wave interference EMI (electromagnetic interference) becomes the serious problem. The malfunction by the EMI is the phenomenon that must not happen at the point (e.g., a plane and a car) that seems to affect human life in particular.
