Title:
SIGNAL TRANSMISSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2014/208624
Kind Code:
A1
Abstract:
A first circuit on the signal transmission side is provided with a first and a second semiconductor switching element which are driven alternatively ON and OFF in accordance with multiple signals and which transmit a power source voltage or a reference potential of the first circuit to a second circuit. Further, the second circuit, on the signal receiving side, is provided with: a voltage conversion circuit which includes a common mode noise filter for removing common mode noise superimposed on the voltage transmitted via the first and second semiconductor switching elements, and which generates a first and second pulse signal that depend on the aforementioned transmitted voltage; a latch circuit which latches the first and second pulse signals with the first and second pulse signals as the clock, respectively; and a signal analysis circuit which analyses the first and second pulse signals latched in the latch circuit and generates an output signal depending on the type of the signals.
