A driving method which makes it possible to use conventional digital driver ICs and to achieve multi-gray displays with simple computation is proposed. Low cost video-rate 320/spl times/240 8-gray STN-LCD has been realized using the proposed method which adopts multi-line selection scheme.

In order to provide high breakdown voltage in thin-film SOI devices, a linear doping profile in the drift region is needed. The linear doping profile can be obtained by using a lateral variation doping technique. In this technique, a smeared-out dopant distribution is implemented through the use of a sequence of small opening slits in the oxide with subsequent impurity implantation and drive-in processes. In this paper, an analytical model is presented to describe the impurity distribution of a finite width impurity source which is used to form the linear doping profile. This model provides a basis for determination of the slits width and silts spacing which are required to implement the linear doping profile.

The development of accurate, low-cost, rapid prototyping techniques for analog circuits has been attempted at various times using variety of implementation formats over the past several decades with varying degrees of success. Commercial products introduced recently, along with progress made at University research labs, indicates renewed interest and further accomplishment in achieving this goal. This paper reviews past work in the area from both universities and industry, provides a status report on the state of activities world-wide, and attempts to forecast developments in prototyping analog and mixed-signal systems one can expect in the near future.

A digital input driver was designed and integrated with an active matrix nematic liquid-crystal-on-silicon (LCOS) display. Fabricated by conventional 2-/spl mu/m CMOS technology, the driver in the periphery of the active matrix can easily incorporate versatile electronic functions into the silicon backplane. This integration makes the LCOS display easier to be interfaced with different image sources of various formats and, hence, leads to a versatile display system.

We describe a connectionist architecture which shows promise in obtaining the global optimal solution to the classical minimum spanning tree problem in a time independent of the problem size. Using commonly available analogue electronic components, a network prototype was found to give the global optimal solution within the microseconds range. Simulation results and limiting factors of the performance of analog and VLSI implementation circuits are discussed.

The Co/a-SiGe/Si solid state reaction has been studied in this paper. The experimental results demonstrated the simultaneously SiGe/Si solid phase hetero-epitaxy and CoSi/sub 2//SiGe contact formation. The SiGe crystallization is a result of the Ge rejection and interdiffusion with Si during the Co/a-SiGe/Si ternary interaction.

This paper describes the implementation of a Viterbi decoder with a modified list-of-two List Output Viterbi Algorithm (LOVA) which is used to decode variable data rate frames in Code Division Multiple Access (CDMA) mobile stations. It performs the decoding of convolutional code k=9, rate=1/2 for fall, half, quarter, and eighth data rate frames. This Viterbi decoder is a part of a CDMA base-band processor used in an IS-95 cellular and Personal Communication System (PCS) mobile terminal.

High indium concentration In/sub 0.65/Ga/sub 0.35/As/Al/sub 0.33/Ga/sub 0.67/As superlattices on GaAs substrates are useful for modulators and optical communication applications. This is due to the lowest loss 1.55 /spl mu/m optimum wavelength for operation of fiber optic systems. The optical parameters such as absorption coefficient and change in refractive index with applied electric field are investigated.
