Abstract: A common data line serially connects a first dot memory group and a second dot memory group in layout order of driven devices so as to form each pair. First word lines are connected to the first dot memory group. Second word lines are connected to the second dot memory group. A data writing section supplies the correction values for the first dot memory group and the correction values for the second dot memory group while shifting the timing and supplies writing signals to the first word lines and the second word lines at predetermined timing. A chip area is reduced and costs of a driving apparatus is reduced.

Abstract: Two TEGs are used for acquiring FET capacity. A first TEG includes a first base section of the same shape and same dimensions as a gate electrode of the FET whose capacity is to be acquired, and a first additional section added at one end of the first base section. A second TEG includes a second base section of the same shape and same dimensions as the first base section, a second additional section having the same shape and same dimensions as the first additional section and added to one end of the second base section, and a third additional section having the same shape and same dimensions as the second additional section and added to the other end of the second base section. The capacity between the body and source or between the body and drain of the FET whose capacity is to be acquired is estimated from the difference in capacity between the body and source or between the body and drain of the first TEG and second TEG.

Abstract: There is an apparatus for predicting wave propagation characteristic of a multiple antenna system, including: a transmission position calculator for calculating transmission positions of multiple transmitting antennas; a wave propagation path searcher for searching for a wave propagation path for each of a plurality of image antennas generated for each of said multiple transmitting antennas; a reflection electric field calculator for calculating a partial reflection electric field on the searched propagation path; and a received power calculator for calculating a received power based on the calculated partial reflection electric field.

Abstract: An apparatus for demodulating an analogue input signal comprises a hard limiter stage (4) for converting the signal to a two level signal. A digital down converter/low pass filter stage (6) converts the signal to a base band signal, and a symbol synchronization stage (8) extracts symbol timing. An instantaneous phase detector (10) calculates the instantaneous phase of the one or more symbols associated with the input signal. If the input signal has been modulated according to a pi/4DQPSK, pi/2DBPSK, GMSK, or a GFSK modulation scheme, a differential detector (12) determines a difference in the phase between adjacent symbols, a coarse frequency offset compensation stage (14) applies a compensation signal to compensate for frequency offset, and a frequency offset estimation stage (16) updates this compensation signal. A demapper (18) generates a demodulated output signal after compensation by the frequency offset compensation stage.

Abstract: Disclosed herein are a keypad having a function button used to easily input characters in cellular phones and other character input devices and a method of easily inputting various languages and letters using the function button. The function button is set independently of a menu button. Whenever the function button is pushed in a default character input mode, the default character input mode is changed to an upper-case letter input mode, a lower-case letter input mode, a sentence mark input mode, a numeral input mode, a special character input mode and other language input modes. After a desired character has been inputted in a corresponding changed input mode, the function button is pushed to rapidly return to the initial character input mode. Various sentence marks can be effectively inputted using the function button.

Abstract: A bidirectional Trench Lateral Power MOSFET (TLPM) can achieve a high breakdown voltage and a low on-resistance. A plurality of straight-shaped islands having circular portions at both ends are surrounded by a trench arrangement. The islands provide first n source regions and a second n source region is formed on the outside of the islands. With such a pattern, the breakdown voltage in the case where the first n source regions are at a high potential can be higher than the breakdown voltage in the case where the second n source region is at a high potential. Alternatively, in the case of not changing the breakdown voltage, the on-resistance can be reduced.
