The wake-up circuit includes a second comparator coupled to the input signal and con - figured to compare the input signal to a second comparison value. The wake-up circuit further includes an exclusive OR gate. A first input of the exclusive OR gate is coupled to an output of the first comparator. A second input of the exclusive OR gate is coupled to an output of the second comparator. The wake-up circuit also includes a tunable charge pump coupled to an output of the exclusive OR gate and configured to convert a signal from the exclusive OR gate to a DC value to wake up a circuit being monitored.
