Abstract: A current source is provided to supply stable currents insensitively to environmental change while obtaining wide output ranges even at low power supply voltage, thereby preventing excessive power consumption. A voltage regulator determines an output voltage by using an input voltage. A plurality of transistors(40) is connected in parallel between the output terminal of the voltage regulator and a ground. A detecting unit(30) selects any one of the plurality of transistors on the basis of phase changes in the delayed clock. The selected transistor is operated.

Abstract: PURPOSE: A channel interference avoidance method and system thereof in a single channel sensor network are provided to predict interference through the collection of interference information of neighbor nodes. CONSTITUTION: If an ED(Energy Detection) scan is operated, a specific node calculates WMA(Weighted Moving Average)(403,405). The specific node exchanges the WMA for WMA of a neighbor node(407).
