Reduced supply voltage in digital and analog circuits is considered to be one of the best methods for achieving real low power dissipation circuits. In this paper, pass-transistor logic with suppressed internal voltage-swing is investigated and analyzed. A proposal on a reduced swing 14-bit parity generator and carry generation blocks of a parallel full adder are also given. In addition, optimization on propagation delay can be achieved by proper tapering of the dimension of the transistors.","PeriodicalId":425138,"journal":{"name":"1995 IEEE TENCON.

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.","PeriodicalId":425138,"journal":{"name":"1995 IEEE TENCON.

Design study of passivation ledge in AlGaAs/GaAs heterojunction bipolar transistors AlGaAs/GaAs异质结双极晶体管钝化边缘设计研究

However, the design of the ledge and its effectiveness on base current reduction need to be further investigated. In this paper, HBTs with different ledge structures are analyzed with 2-dimensional simulation. The results indicate that a thinner ledge provides better suppression of electron lateral (horizontal) diffusion in the base, and therefore reduces the electron component in base current. Optimization of the ledge design and GaAs surface passivation process is essential for device reliability, too. A new device structure with heavily doped extrinsic base layers is proposed to further improve the base current.","PeriodicalId":425138,"journal":{"name":"1995 IEEE TENCON.
