摘要 |
An electronic device according to one or more embodiments of the present invention comprises an output line, a current mirror circuit and a comparator. Current signals from a plurality of signal sources are output to the output line. The current mirror circuit is electrically connected to the output line. The comparator is configured to compare a mirrored current signal from the current mirror circuit with a reference current signal. The comparator is configured to output a signal representing a comparison result of amplitudes of the mirrored current signal and the reference current signal.
