Abstract
According to an embodiment, a current monitoring circuit includes a signal shaping unit configured to receive a current sense signal and provide a modified current signal; a filter configured to receive the modified current signal and to provide a respective filtered signal; a comparator configured to receive the filtered signal and a threshold value and to indicate when the filtered signal exceeds the threshold value. The signal shaping unit is configured to calculate a level of the modified current signal from a corresponding level of the current sense signal in accordance with non-linear function.
