摘要:
There is provided a negative differential resistance amplifier comprising a negative differential resistance transistor having negative input conductance by utilizing resonant tunneling effect. The transistor is electrically connected to a signal source circuit in cascade, and the following relation is established in the negative differential resistance amplifier:0 0) indicates a conductance measured when viewed from an interface between the negative differential resistance transistor and the signal source circuit to the signal source circuit, -gi (gi>0) indicates a conductance of the negative differential resistance transistor, and G (G
