Abstract: Disclosed are a spike neural network apparatus based on a multi-encoding and an operating method thereof. The method of operating a spike neural network (SNN) apparatus that performs a multi-encoding, includes receiving an input signal by an encoding module, performing a rate coding and a temporal coding on the received input signal by the encoding module, generating an SNN input signal based on the performance result of the rate coding and the temporal coding, and transmitting the generated SNN input signal to a neuromorphic chip that performs a spike neural network (SNN) operation.

Abstract: Disclosed is a transmitter which includes a channel driver that includes a pull-up transistor and a pull-down transistor connected between a power node and a ground node and outputs a voltage between the pull-up transistor and the pull-down transistor as a transmit signal, and a pre-driver that controls the pull-up transistor and the pull-down transistor in response to a driving signal and controls the channel driver such that the transmit signal is overshot at a rising edge of the driving signal and the transmit signal is undershot at a falling edge of the driving signal.
