Abstract
A sleep-wake control circuit using a D-type flip-flop with a Schmitt trigger to detect pulse wake-up signal transitions. The sleep-wake control circuit comprises a sleep command input channel, a wake command input channel, and a D-type flip-flop. The D-type flip-flop is configured to receive a signal to switch to sleep mode from the sleep command input channel as a clock signal and to receive a wake event signal to switch to wake mode from the wake command input channel as a clear signal, such that a wake event signal from the wake command input channel takes priority over a sleep event signal from the sleep command input channel. The sleep command input channel and the wake command input channel are configured to include Schmitt triggers so as to detect pulse input signals.
