The invention discloses a carbon nanotube field effect transistor (CNFET) type double-edge pulse type JKL trigger. The CNFET type double-edge pulse type JKL trigger comprises a double-edge pulse signal generator, thirty-first CNFET tubes, six NTI gate circuits with the same circuit structure, six PTI gate circuit with the same circuit structure, a first ternary phase inverter and a second ternary phase inverter, wherein the first ternary phase inverter and the second ternary phase inverter have the same circuit structure. The CNFET type double-edge pulse type JKL trigger has the advantages: a clock signal is generated by utilizing the double-edge pulse signal generator; by combining switching operation of a multi-value logic circuit and high-speed low-power features of CNFET, a purpose of reducing the power consumption is achieved when the working speed of the JKL trigger is improved; and based on experiment results, the JKL trigger provided by the invention has a correct logic function and remarkable characteristic of low power consumption.
