    Abstract: Provided is an electronic circuit for implementing a generative adversarial neural network. The electronic circuit includes a spike converter, a spike image generator, a spike image converter, and an image discriminator. The spike converter generates a first signal including spike signals. The number of the spike signals is determined based on first data associated with second data within a reference time interval. The spike image generator generates a second signal including spike signals being selected based on a weight among the spike signals of the first signal. The image converter converts the spike signals of the second signal to generate third data being represented in an analog domain. The image discriminator provides the spike image generator with result data being associated with a difference between a value of the third data and a value of the second data. The image generator determines the weight based on the result data.

    Abstract: An interface device for performing on-off keying (OOK) modulation and a transmitter using the interface are disclosed. The interface device includes a first inverter and a second inverter. The first inverter outputs a signal to a first output terminal based on a digital baseband signal when the digital baseband signal is applied thereto. The second inverter outputs a signal to a second output terminal based on a signal obtained by inverting the phase of the digital baseband signal when the digital baseband signal is applied thereto.
