Abstract

A power detection circuit is provided. The power detection circuit includes a comparator circuit operative to generate an output signal in response to an input signal. The output signal is configured to change from a first value to a second value in response to the input signal attaining a first threshold value. The output signal is configured to change from the second value to the first value in response to the input signal subsequently attaining a second threshold value. A current limiting circuit is connected to the comparator circuit and operative to limit a leakage current of the comparator circuit.
