Abstract:
|
The immunity of operational amplifiers is a trend
topic for electromagnetic compatibility EMC community.
Radiofrequency interference is usually applied to the operation
amplifier and the voltage offset is monitored as a parameter to
evaluate the EMC degradation. However, this method does not
provide enough information to know the probability of failure to
electromagnetic interference of the devices. In this paper, an
alternative statistical analysis based on the Weibull distribution is
used to analyze the electromagnetic immunity performance of
operational amplifiers under different frequency interferences
and modulation index. The results confirm the feasibility of the
Weibull distribution to evaluate the radiofrequency interference
RFI behavior. |
