摘要： A femtocell, a femtocell gateway and an access rejection method thereof are provided. A wireless network system comprises a wireless device, a plurality of the femtocells, the femtocell gateway and a core network server. The wireless device has a Subscriber Identification and the core network server stores a Closed Subscribers Group Identification of the femtocells. The femtocell gateway receives an access rejection message corresponding to the Subscriber Identification of the wireless device from the core network server, and transmits the access rejection message to the femtocells. Each femtocell records the Subscriber Identification in a rejection list thereof, and it is capable of adding/deleting Subscriber Identifications in its rejection list. When each femtocell receives the Subscriber Identification of the wireless device again and determines that the Subscriber Identification has been recorded in the rejection list thereof, each femtocell immediately terminates a wireless connection from the wireless device.

摘要： A resistor unit is adapted for use in a constant current source circuit or a temperature compensating circuit for providing temperature compensation to a constant voltage reference circuit. The resistor unit includes at least one first resistor, and at least one second resistor coupled to the first resistor. One of the first and second resistors is a positive temperature coefficient resistor. The other one of the first and second resistors is a negative temperature coefficient resistor. Because a temperature characteristic of the first resistor is opposite to that of the second resistor, an effective resistance of the resistor unit changes in a relatively narrower range with temperature.

摘要： A spread spectrum clock generating apparatus is disclosed. The spread spectrum clock generating apparatus includes a phase lock loop module and a spread spectrum module. The phase lock loop module is used for dynamically tuning frequency of an output clock. The spread spectrum module includes a counter, a plurality of delta-sigma counters and a data shifter. These delta-sigma counters accumulate input signals, and enable a first overflow signal while accumulation of a last stage delta-sigma counter is overflowed. The frequency of the output clock can be tuned dynamically according to the first overflow signal, and the spectrum of the output clock can be spread.
