The apparatus is a wake-up circuit including a first comparator coupled to an input signal and configured to compare the input signal to a first comparison value. The wake-up circuit includes a secondcomparator coupled to the input signal and configured 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 chargepump 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. 装置是包括第比较器的唤醒电路，第比较器耦合到输入信号并且被配置为将输入信号与第比较值进行比较。该唤醒电路包括第二比较器，其耦合到输入信号并且被配置为将输入信号与第二比较值进行比较。该唤醒电路还包括异或门。异或门的第输入耦合到第比较器的输出。异或门的第二输入耦合到第二比较器的输出。该唤醒电路还包括可调谐电荷泵，其耦合到异或门的输出并且被配置为将来自异或门的信号转换为DC值以唤醒正在被监控的电路。
