摘要： An electronic circuit capable of efficiently transmitting signals in a case where signals are transmitted over substrates with three or more substrates three-dimensionally mounted. In the present invention, LSI chips are stacked in three layers, and a bus is formed over three chips. The first through the third transmitter coils 13a, 13b, 13c and the first through the third receiver coils 15a, 15b, 15c are formed by wiring on the first through the third LSI chips 11a, 11b, 11c.

摘要： An electronic circuit capable of reducing crosstalk to such a degree that the crosstalk can be substantially disregarded even where a plurality of communications channels are juxtaposed in close proximity to each other when achieving communications between substrates by inductive coupling. The transmitter coils 11 are placed on a lower chip and the receiver coils 12 are placed on an upper chip, and where it is assumed that the distance between the chips is X, and the distance between the communications channels is Y (that is, the horizontal distance between the coil centers), there exists a position, where the magnetic flux density in the receiver coils 12 resulting from the transmitter coils 11 becomes zero (0), at a predetermined Yo. That is, because large crosstalk occurs when Y is small, and small crosstalk of an inverted symbol occurs when Y is large, in the meantime, there will exist a position, where the value obtained by integrating the magnetic flux density B in the receiver coils 12 becomes zero (0), without fail. No crosstalk is theoretically generated at the position.

摘要： The invention provides an electronic circuit capable of simplifying a transmitter circuit and yet realizing low-voltage drive and low power consumption where communications between substrates are realized by inductive coupling. As the transmission data Txdata are turned from LOW to HIGH, the transistor T1 is turned from OFF to ON, and at the same time, the transistor T2 is turned from ON to OFF, wherein the current IT is caused to flow to the transmitter coil 14, and the capacitor 15 is charged. As the capacitor 15 is sufficiently charged, the current IT stops flowing. As a result, a pulse current of a triangular waveform is flown to the transmitter coil 14. Next, as the transmission data Txdata are turned from HIGH to LOW, the current IT is inversely flown to the transmitter coil 14, and the capacitor 15 is discharged, wherein a pulse current having a triangular waveform of reversed polarity is flown to the transmitter coil 14. Since discharge of the capacitor 15 is utilized to cause a pulse current of reversed polarity to flow, no power source current is used; subsequently, power can be saved.

摘要： The invention provides an electronic circuit capable of carrying out communications by inductive coupling with minimum power consumption between substrates. In the electronic circuit according to the invention, although the amplification factor of the amplifier 10a is 1, the amplification factors of the amplifiers 10b through 10d are, respectively, 2, 4 and 8. Amplification is carried out at the amplification factors 1 through 15 (=1+2+4+8) as a whole by a combination thereof. The transmit power control register 21 outputs ON and OFF signals to the respective amplifiers 10a through 10d so as to bring about transmit power responsive to the distance to a substrate having a receiver coil which is a destination of transmission (that is, the distance between a transmitter coil and a receiver coil), in further detail, so as to have an amplification factor by which transmit power proportionate to the distance can be obtained, and selects a combination of the amplifiers 10a through 10d.

摘要： Where communications between substrates are formed by inductive coupling, the invention provides an electronic circuit that is less influenced by magnetic fluxes from a noise source. In the electronic circuit according to the invention, in regard to the transmitter coils and the receiver coils, one coil thereof is composed of the first coil 11a and the second coil 11b. The first coil 11a and the second coil 11b are wound by the same number of times and are connected to each other in series. When a current flows in the arrow direction, if observed so as to face the paper surface of the drawing, the second coil 11b is wound in the left direction while the first coil 11a is wound in the right direction. Where the first coil 11a and the second coil 11b are used as a receiver coil, since it is assumed that magnetic fluxes from a normal noise source enter the first coil 11 and the second coil 11b at the same intensity in the same direction, the magnetic fluxes are canceled each other out by the first coil 11a and the second coil 11b, which are wound reversely to each other, wherein no electromotive force is generated.
