Abstract: A PLL includes an open-loop automatic frequency calibration circuit. The open-loop automatic frequency calibration circuit includes a frequency detector, first and second sinks, a comparator and a bank selector. The frequency detector generates an up-signal and a down-signal responding to a frequency difference between a first phase difference signal having a phase difference from a reference oscillation signal and the second phase difference signal having a phase difference from a frequency division oscillation signal. The first and second sinks discharge the first and second capacitors respectively responding to the up-signal and the down-signal. The comparator compares voltages of the first and second capacitors. The bank selector selects a bank according to binary search, selects an optimum bank among two banks lastly searched, and outputs a bank selection signal. The voltage-controlled oscillation changes frequency features thereof in response to the bank selection signal.

Abstract: A power line communication (PLC) network and method, in which a coordinator can be changed. The PLC network includes a coordinator and a standby coordinator. The coordinator performs scheduling coordination in a PLC cell and periodically transmits scheduling information about the scheduling coordination to stations in the PLC cell. The standby coordinator serves as the new coordinator instead of the coordinator when the coordinator does not operate for a predetermined amount of time.

Abstract: Provided is an apparatus and method of displaying power line communication channel information. The apparatus for displaying power line communication (PLC) channel information includes a channel information determining unit which performs PLC channel estimation and determines channel information including a bandwidth which is available for a user in a power line communication network; and a channel information displaying unit which displays the channel information to the user. Since channel information is determined through channel estimation and displayed to a user, it is possible to easily check whether a channel can be used before installing a power line communication (PLC) device. In an application, information on kinds of a service which can be selected by the user or expected quality of the service can be previously checked. Accordingly, the user can know whether the communication can be performed, without installing a communication device or executing a communication application which requires much time and effort. Accordingly, it is possible to reduce time and effort necessary for finding an adequate communication point.

Abstract: Isolation regions for a semiconductor layer of a semiconductor-on-insulator substrate are fabricated by forming a patterned implantation mask on the semiconductor layer. The patterned implantation mask includes mask sidewalls. An implantation masking film is formed on the sidewalls of the patterned implantation mask. Ions are implanted into the semiconductor layer, using the patterned implantation layer and the implantation masking film as a mask, to thereby form a doped region in the semiconductor layer. Sidewall spacers are formed on the implantation masking film, opposite the patterned implantation mask. The doped region between the sidewall spacers is etched to thereby define a trench in the semiconductor layer between the sidewall spacers and a doped edge layer in the semiconductor layer which extends from the trench to the implantation masking film. Insulating material is then formed in the trench.
