Patent ID: 8913687

Claim:
A signal transmission system comprising: a first chip comprising: a transmission module configured to receive an input signal and generate a rising pulse signal and a falling pulse signal in response to a waveform of the input signal, wherein the rising pulse signal corresponds to rising edges of the input signal, and the falling pulse signal corresponds to falling edges of the input signal; a first transmission unit coupled to the transmission module, located on a surface of the first chip, and configured to transmit the rising pulse signal; and a second transmission unit coupled to the transmission module, located on the surface of the first chip, and configured to transmit the falling pulse signal; and a second chip configured opposite to the first chip, the second chip comprising: a first reception unit located on a surface of the second chip, the first reception unit corresponding to the first transmission unit and being configured to receive the rising pulse signal; a second reception unit located on the surface of the second chip, the second reception unit corresponding to the second transmission unit and being configured to receive the falling pulse signal; and a reception module coupled to the first reception unit and the second reception unit and configured to output a recovery signal according to the rising pulse signal and the falling pulse signal.
