Abstract: Provided are a human body communication device and an operating method of the same. The human body communication device according to an embodiment of the inventive concept includes a first electrode, a second electrode, a transmitting circuit, a receiving circuit, a ground electrode, and a switch. The transmitting circuit generates a first signal in a transmitting mode and transmits the first signal to the first electrode. The receiving circuit receives a second signal from the first electrode in the receiving mode. The receiving circuit includes a differential amplifier that amplifies a difference between a voltage level of a first input terminal depending on the second signal and a voltage level of a second input terminal. The switch electrically connects the second electrode and the ground electrode in the transmitting mode, and electrically connects the second electrode and the second input terminal in the receiving mode.

Abstract: Provided is a receiver. The receiver according to the inventive concept includes a first filter circuit, a second filter circuit, and an amplifier. The first filter circuit provides a first path for first frequency components below first cutoff frequency of input frequency components and passes second frequency components except for the first frequency components of the input frequency components through second path. The second filter circuit attenuates third frequency components below a second cutoff frequency of the second frequency components. The amplifier amplifies the second frequency components including the attenuated third frequency components.

Abstract: Disclosed is an interpolation filter based on time assignment algorithm. An interpolation filter comprises an enable signal generating part generating enable signals for operation of the interpolation filter, an input value generating part generating input values, a first calculating part generating a first output value based on a first enable signal and a first input value, a second calculating part generating a second output value based on a second enable signal and a second input value, and an output value selecting part selecting a final output value among the first output value and the second output value. Thus, continuity of output data can be guaranteed, and hardware can be shared by using time assignment algorithm so that a total size of the interpolation filter can be reduced.
