A digital circuit comprises a plurality of functional circuits and a finite state machine. Each functional circuit comprises a digital macro, a resistance control device and at least one device with capacitance. The digital macro is coupled to a ground. The resistance control device is electrically connected between the digital macro and an always-on power mesh. The at least one device with capacitance is electrically connected between the resistance control device and the ground. The finite state machine is electrically connected to the resistance control device, and is configured to adjust the resistance of the resistance control device.

Digital circuit

A method for detecting a capacitive load circuit of a remote powered device in a communication system is disclosed. The communication system includes the power source device being coupled to the remote powered device by a cable. the method comprises: providing a first current to the capacitive load circuit of the remote powered device; charging or discharged the capacitive load circuit of the remote powered device according to the first current; and detecting a voltage value or a slope of a first voltage of the capacitive load circuit to generate a detection result. The method further comprises: providing an operation voltage to the remote powered device.

Control, detection apparatus of power of network and detection method

A communication system capable of adjusting power consumed thereby is adapted for receiving connection information. The communication system includes first and second transceiving devices. The first transceiving device includes a transmitting end and a service end for receiving the connection information. The second transceiving device includes a receiving end capable of forming a communications link with the transmitting end. A power state of each of the first and second transceiving devices is switchable between a power-supplied mode and a power-saving mode. The power state alters status of the communications link.
