A body channel communication method is disclosed including the following steps. Whether or not a body channel is established is detected. When that a body channel is established is detected, a check packet is received from an electrical device, which is at another end of the body channel, through the body channel. A current interference power of the body channel is estimated according to the received check packet. A current transmission mode for the body channel is obtained according to the current interference power. Data is transmitted through the body channel, which is set to the current transmission mode. Further, a body channel communication device is also disclosed.

A delay cell includes a first inverted transistor pair, a second inverted transistor pair and a plurality of delay units. The first inverted transistor pair is used to receive an input signal. The second inverted transistor pair is electrically cross-coupled to the first inverted transistor pair and cross-controlled by the first inverted transistor pair. The delay units are cascaded between the first inverted transistor pair and between the second inverted transistor pair, thereby providing a plurality of signal propagation delays sequentially, wherein the input signal is delayed for a pre-determined time by the first inverted transistor pair, the second inverted transistor pair and the delay units which are operated sequentially, thereby creating an output signal corresponding to the pre-determined time. A digitally controlled oscillator including the aforementioned delay cells is provided.
