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 system-on-chip. A central controller is configured to, in response to a request from a host, generate a first signal for requesting error information related to an error from a design of an IP. A local controller is configured to generate a second signal including the error information of the target IP if the request from the host is determined to be for the target IP based on the first signal.

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: A low power system on chip for supporting partial clock gating is provided. The system on chip includes a network on chip including a first CG-network interface module, a second CG-network interface module, and a clock gating control module, a first IP block that communicates through the first CG-network interface module, and a second IP block that communicates through the second CG-network interface module. The clock gating control module receives a clock gating request from the first IP block, outputs a communication control signal to the second CG-network interface module in response to the received clock gating request, and performs a clock gating operation for a clock signal in response to the received clock gating request to selectively deliver the clock signal to the second IP block.
