Реферат: A peak detector (900) for a synchronized switch harvesting on inductor converter comprises a comparator (930) and a filter (905) configured to filter an input signal to the peak detector and to provide a filtered signal to an input of the comparator (930). The filter (905) has a differentiating transfer characteristic for a low frequency range and an integrating transfer characteristic for a high frequency range of the input signal so that peaks of the input signal to the peak detector which have primarily frequency components in the low frequency range cause a relatively strong variation of the filtered signal and peaks of the input signal to the peak detector which have primarily frequency components in the high frequency range are substantially integrated and cause a relatively weak variation of the filtered signal. The relatively strong variation of the filtered signal crosses a comparator threshold of the comparator (930). The comparator (930) is configured to generate an output signal that indicates a relation of the filtered signal with respect to the comparator threshold.
