Anchor carrier in a multiple carrier wireless communication system
Multiple downlink (DL) and uplink (UL) carriers can enhance wireless communication between nodes and user equipment (UE). Among the carriers, it is beneficial to have some special, by configuration designated carriers to provide synchronization, system information, paging, data and control for multi-carrier enabled UEs.

Series-connected FETs in active linear mode
The addition of gate bias resistors substantially balances the voltage across any number of series-connected FETs, while the feedback control of the gate-source voltage of one FET controls the current through all of the FETs.
