本文研究了在全并行A/D转换器领域中GaAlAs/GaAs异质结双极晶体管(HJBT)工艺的应用前景。为了预测HJBT的前景,与用现代硅工艺可达到的最好性能水平进行了比较。用每一种工艺研制了最佳的锁存比较器,并且进行了SPICE模拟,以便决定其能达到的最大采样率和大信号模拟带宽。在我们进行上述两种工艺的比较时,有这样的一些工艺模式可选用,一种是近期开发阶段的标准的1μm.极工艺与4μm.JBT工艺;另一种是早期开发阶段改进的1μm.双极工艺与2.5μm.JBT工艺。这样使得随时间流逝的性能改善趋势亦可进行比较。

Energy flexibility can address the challenges of large scale integration of renewable energy resources and thereby increasing im.alance in the power system. Flexible power system.can provide reliable supply, low electricity cost and sustainability. Various situations and factors influence the adoption of the flexibility solutions, such as flexible electricity generation, dem.nd-response, and electricity storage. This paper tries to analyze the current energy flexibility solutions and the factors that can influence the energy flexibility adoption. This paper tak.s Philippines as case study to provide an overview of the current condition of the Philippines＇ power system.and discuss the energy flexibility in the Philippines＇ power system. A further discussion and recom.endation is conducted in the end of the paper.

Energy flexibility in buildings will play an im.ortant role in the sm.rt energy system. Office buildings have m.re potentials to provide energy flexibility to the grid com.ared to other types of buildings, due to the existing building m.nagem.nt, control system. and large energy consum.tion. Consum.rs in office buildings （building owners/m.nagers and occupants） tak. a m.in role for adopting and engaging in building energy flexibility. This paper provides a system.tic review of consum.r central energy flexibility in office buildings with the discussion of social, technical and business aspects. This paper clarifies the correlations of consum.rs＇ concem., external influential factors, energy flexibility resources and technology with eight hypotheses. This paper suggests that technical solutions with the integration of distributed energy resources, building m.nagem.nt and control system.can boost energy flexibility in the office buildings.
