摘要： An apparatus for receiving a wideband pulse signal in a communication channel using the human body is provided to lower receive sensitivity to the utmost by separating a signal amplification function from a comparison function through a wideband symmetric technique and to reduce the occupation area by removing the necessity of an external reference voltage. A wideband pulse signal receiver in a communication channel using the human body is composed of a bias circuit(42), a wideband pre-amplifier(44), a Schmitt trigger(46), and a reverse buffer(48). The bias circuit(42) sets a DC bias for a wideband pulse signal, transferred and received through the human body used as a data transfer medium. The wideband pre-amplifier(44) provides a high voltage gain for the DC bias-set wideband pulse signal over a wide frequency band. The Schmitt trigger(46) triggers the pulse signal, amplified through the wideband pre-amplifier(44), to a stable voltage state by using symmetric threshold voltage. The reverse buffer(48) reverses the triggered pulse signal and outputs a digital signal of which the phase is matched with the received input signal.

摘要： A wireless audio transmitting and receiving apparatus using a human body is provided to convert an audio signal outputted from a portable audio player by using digital audio interface technique without using a wire or an antenna, transmit the converted audio signal at high speed through the human body by using only one signal electrode, and receive an audio signal transmitted through the human body to allow a user to listen to the received audio signal. A transmitting unit(40) converts an audio signal outputted from an audio source device by using digital audio interface technique, and transmits the converted audio signal to a human body. A receiving unit(50) recovers data transmitted through the human body by using the digital audio interface technique, and outputs an audio signal. The transmitting unit(40) includes a transmitting electrode(44), an A/D converter(41), a digital audio interface transmitter(42), and a transmitting circuit(43). The transmitting electrode(44) contacts to the human body. The A/D(Analog to Digital) converter(41) converts the audio signal outputted from the audio source device into a digital signal. The digital audio interface transmitter(42) converts the digital signal converted through the A/D converter(41) into serial digital data of a frame unit in which timing information of a clock is embedded. The transmitting circuit(43) induces an electric field through the transmitting electrode(44) for the serial digital data converted in the digital audio interface transmitter(42).
