    摘要： A rijndael block cipher apparatus including an operational unit that efficiently performs a round operation for encrypting/decrypting a rijndael block cipher and an encryption/decryption method thereof are disclosed. The rijndael block cipher apparatus is mounted in a mobile terminal such as a cellular phone and a PDA or a smart card, which requires a high-rate and small-sized cipher processor, and can encrypt and decrypt important data that requires security at high speed and perform the round operation with respect to upper 64 bits and lower 64 bits which are divided from 128-bit input data. Thus, the cipher apparatus can reduce the time required for encryption/decryption of the rijndael block cipher and the size of the apparatus.

    摘要： Disclosed herein is a flyback converter with a synchronous rectifier which is applied to a power supply of a portable computer such as a notebook PC. The flyback converter is operated in a critical conduction mode to turn on/off a main switch at a zero crossing point of an output voltage. The flyback converter is also adapted to supply a driving voltage to a synchronous switch using the output voltage. Therefore, there is no need for a secondary auxiliary coil of a transformer and for a Schottky diode to be connected in parallel with the synchronous switch, resulting in simplification in circuit design.

    摘要： Disclosed herein is a broadband internal antenna. The broadband internal antenna includes a first radiator and a second radiator. The first radiator has a radiation part in which one or more coils having different pitch intervals are connected in series to each other. The second radiator has at least one conductive strip line arranged parallel to the longitudinal direction of the first radiator. Current flowing thorough the first radiator and current flowing through the strip lines form current paths in different directions, so that a certain broadband can be set using mutual Electromagnetic (EM) coupling.
