Abstract
Disclosed are a human body communication receiver and an operating method thereof, which may effectively remove low frequency noise. The human body communication receiver according to the present disclosure includes a receiving electrode, a virtual electrode, a filter circuit that is connected between the receiving electrode and the virtual electrode, and removes low frequency noise from a signal received through the receiving electrode to generate a high frequency signal, a low frequency reconstruction circuit that is connected to a rear end of the filter circuit and reconstructs a low frequency baseband signal by rectifying the high frequency signal, and an amplifying circuit that is connected to a rear end of the low frequency reconstruction circuit, and amplifies the low frequency baseband signal.
