Patent attributes
an electronic circuit according to an embodiment includes: a generation circuit generating a first clocksignal and a second clocksignal delayed from the first clocksignal; a first coupler transmitting one of the first and the second clocksignals by electromagnetic coupling; a first converter driven by the transmitted clocksignal and converting a first input signal into a first signal of a frequency corresponding to the transmitted clocksignal; a second coupler transmitting the first signal by electromagnetic coupling; a second converter converting the first signal into a second signal of a frequency corresponding to the first input signal with the other of the first and the second clocksignals; an output device outputting the second signal; and a protection circuit connected to a line through which the one of the first and the second clocksignals is transmitted between the first coupler and the first converter.
