    • PURPOSE: To obtain a level converting circuit with low power consumption b combining a bipolar transistor (TR) and an MOS TR to attain high speed operation with less number of components.
      CONSTITUTION: When an input terminal Q
      1 is brought into H level and a Q
      2 is ito L level, a TRT
      2 is turned off and MOSTRsM
      1 , M
      2 are turned off. Since a constant current flows to an MOSTRM
      3 by a fixed bias a potential at an output terminal O goes to a ground level. When the terminal Q
      1 is brought into L level and the Q
      2 is to H level, the TRT
      1 is turned off and the TRT
      2 is turned on and the MOSTRsM
      1 , M
      2 are turned o. Since a current flowing between the source and drain of the TRM
      2 is set larger than the current flowing between the source and draiN OF Te MOSTRM
      3 , when the TRM
      2 is turned on, the potential at the terminal O goes to H level. A current flows only for the moment when the potential at the terminal O is switched from the H to L level and only a current for the constant current's share of the TRM
      3 flows even when the level is switched from L to H, then the power consumption is less.

    • 目的:获得具有低功耗b的电平转换电路b,组合双极晶体管(TR)和MOS TR,以较少数量的元件实现高速运行。 构成:当输入端子Q1进入H电平且Q2为I电平时,TRT2关闭,MOSTRsM1,M2关断。 由于恒定电流通过固定偏压流向MOSTRM3,所以输出端子O处的电位达到地电平。 当端子Q1为L电平且Q2为H电平时,TRT1截止,TRT2导通,MOSTRsM1,M2转为o。 由于在TRM2的源极和漏极之间流动的电流被设置为大于在源极和源极之间流动的电流,所以当TRM2导通时,端子O处的电位变为H电平。 A电流仅在端子O的电位从H切换到L电平的时刻流动,并且仅当电平从L切换到H时,TRM3的恒定电流份额的电流才流动,则功耗 少了

    • PURPOSE: To decrease the delay time of the titled circuit by adopting a different gate drive voltage to each FET constituting a CMOS inverter to eliminate a multiple connection of the CMOS inverter and prevent a through-current at the steady state.
      CONSTITUTION: The CMOS inverter consisting of a level shift emitter follower comprising a transistor (TR)Q
      4 , of FETs M1, M2 of a current switch comprising TRs Q
      2 , Q
      3 and Q
      6 is provided. Then a gate drive voltage being a prescribed value from the VCC at OFF-state is applied to the M1 and a gate drive voltage being a prescribed value from a VEE at OFF-state is fed to the M2 respectively so as not to drive gates of a pMOSFET-M1 and an nMOSFET-M2 by the same voltage. As a result, a complete CMOS level is obtained by one stage of the CMOS inverter. Further, the through-current of the steady state is prevented completely.
