摘要
研究多值忆阻逻辑电路,采用三值忆阻逻辑运算单元,设计了三值CMOS忆阻混合型D锁存器,该三值忆阻逻辑运算单元以CMOS和电阻异质结双极性晶体管(Resistor-Heterojunction Bipolar Transistor,R-HBT)负阻型忆阻器等效模型为核心,构成的三值CMOS忆阻混合型D锁存器包括4个三值忆阻与非单元和1个三值忆阻反相器,结构简单。在忆阻D锁存器的基础上,设计了上边沿触发的三值CMOS忆阻混合型D触发器,该D触发器为主从型结构。PSPICE仿真结果符合三值D触发器的逻辑功能,验证了设计的正确性。
A ternary CMOS hybrid memristor D latch is proposed by using ternary memristor logic operation units.The ternary memristor logic operation unit is composed of CMOS and Resistor-Heterojunction Bipolar Transistor(R-HBT)negative resistance memristor.The ternary CMOS memristor hybrid D-latch consists of 4 ternary memristor NAND units and 1 ternary memristor inverter.A ternary CMOS memristor hybrid D flip-flop is designed based on the memristor D-latch,the D flip-flop owns the master-slave structure and is rising edge-triggered.The PSpice simulation results accord with the ternary D-flip-flop logic,which verifies the correctness of the design.
