摘要： A frequency mixing apparatus with improved voltage gain and linearity is provided. The frequency mixing apparatus includes a transconductor, a separator, and a switching unit. A voltage gain of the transconductor is controllable, and the transconductor converts a Radio Frequency (RF) signal into a current signal under control of a self bias. The separator transfers the current signal to the switching unit. The switching unit outputs a signal having a frequency corresponding to one of a sum and a difference of a frequency of the RF signal and a frequency of a Local Oscillation (LO) signal by performing a switching operation according to the LO signal.

摘要： Disclosed herein are a flash file system and an address translation method. The flash file system includes a file system, a Flash Translation Layer (FTL), and flash memory. The FTL receives Local Block Addresses (LBAs) from the file system, and translates the LBAs into Physical Block Address (PBAs. The flash memory receives the resulting PBAs. The FTL includes a memory block in which a multi-stage clustered hash table for mapping the LBAs to the PBAs is stored, and performs the address translation using the clustered hash table.

摘要： A device for forming partition walls of a plasma display panel is disclosed. This device has a lower plate used for seating the base panel of the plasma display panel thereon, with a partition wall sheet of a predetermined thickness formed on the base panel and a plurality of electrodes arranged on the base panel. A punch, having a plurality of partition wall forming grooves and a plurality of lands formed between the partition wall forming grooves. An electrode holding groove or inclined surface is formed on each of the lands and is used for preventing the electrodes from being undesirably moved during a partition wall forming process. An upper plate is positioned above the punch so as to hold the punch and to move the punch in a vertical direction within a predetermined range. Due to the electrode holding grooves or the inclined surfaces formed on the lands, the device of this invention thus almost completely prevents an undesired movement of the printed address electrodes of the base panel, thus finally allowing a precise arrangement of the partition walls with the address electrodes on the base panel.
