Disclosed is an amplification circuit, which includes a first amplifier that receives an external signal and performs first band pass filtering on the external signal to output a first filter signal, and a second amplifier that receives the first filter signal and performs second band pass filtering on the first filter signal to output a second filter signal, and a frequency pass bandwidth of the second band pass filtering is narrower than a frequency pass bandwidth of the first band pass filtering.
An amplification circuit comprising:
A human body channel-based wireless communication system comprising an amplification circuit which receives an external signal and a control circuit configured to receive the external signal and to generate a control signal for controlling the amplification circuit based on a frequency band of the external signal, and wherein the amplification circuit includes:
A method of operating a human body channel-based wireless communication system including an amplification circuit which includes a first amplifier configured to receive an external signal and to perform first band pass filtering on the external signal to output a first filter signal and a second amplifier configured to receive the first filter signal and to perform second band pass filtering on the first filter signal to output a second filter signal, the method comprising:
