Abstract: A reference voltage generator circuit includes: a first transistor and a second transistor, wherein the first transistor and the second transistor are coupled with each other and are located on a substrate, wherein the first transistor has a first conduction threshold voltage and a first rated voltage, wherein the second transistor has a second conduction threshold voltage and a second rated voltage, wherein the first rated voltage is higher than the second rated voltage; wherein the reference voltage generator circuit is configured to generate a bandgap reference voltage with temperature compensation according to a difference between the first conduction threshold voltage and the second conduction threshold voltage.

Abstract: A method for assigning wireless network transmission resource includes the following steps: at least one contention area is broadcasted. A join message is uplinked to a base station (BS) by at least one client utilizing the contention area. Determine if the join message received by the BS has been interfered with. If the join message received by the BS has not been interfered with, the contention area is assigned to the client. The client utilizes the contention area to upload data.

Abstract: A method for transmitting packets and a network system thereof are provided. In the present invention, each packet entering the network system is added an assigning tag to indicate the arrival time of the packet, and at least two queues in a node of the network system are used for respectively sorting the local packets of the node and the relayed packets of the preceding node. The order of the packet for transmitting can be decided by comparing the assigning tags of the two packets positioned at first order in different queues. Therefore, a condition of First-In First-Out (FIFO) is satisfied in the network system, and the sequence for transmitting packets is arbitrated fair.
