摘要： A transmitter circuit feeds to a transmitter coil, every time transmission data changes in logical value, a current signal in pulse form having a positive or negative polarity that is alternately inverted in response to each change in logical value; and a receiver circuit inputs induction voltage signals each being double pulses having both positive and negative polarities, which have been induced in a receiver coil by the current signal fed to the transmitter coil, to demodulate the transmission data. The receiver circuit includes: an amplifier that amplifies the induction voltage signals of double pulses induced in the receiver coil; and a signal generating unit that, when detecting first single pulses in the induction voltage signals of double pulses amplified by the amplifier, sets up an insensitive period for second single pulses therein, to generate an output signal corresponding to the transmission data, based solely on the first single pulses.

摘要： A signal transmission circuit includes an isolation circuit, first and second grounded gate circuits, first and second MOS transistors, and a comparator. The isolation circuit such as a thin-film transformer outputs complementary first and second output signals, based on an input signal. The first and second grounded gate circuits receive and amplify the first and second output signals, respectively. The first and second MOS transistors are connected between a power supply node and the first and second grounded gate circuits, respectively, for adjusting the first and second output signals. The comparator compares output from the first grounded gate circuit with output from the second grounded gate circuit.
