Spike neuron-based wake-up circuit and operation method thereof

Abstract

Disclosed is a wake-up circuit including a preprocessing unit that generates a first signal by removing noise from an input signal, a comparison unit that generates a second signal based on the first signal and weight data, an output circuit that generates a power signal based on the second signal and an initialization signal, and a micro control unit (MCU) that generates the initialization signal based on a state signal received from the output circuit. The comparison unit includes a spike neuron network structure that generates the second signal by applying the weight data to the first signal. The output circuit supplies power to an external sensor node in response to the power signal.
