Abstract :
Three modes of operation of bulk-semiconductor devices are derived from a small-signal theory: 1) admittance-type negative conductance, 2) impedance-type negative resistance, and 3) nearly frequency-independent negative conductance. Their behavior is in approximate agreement with that of the modes of stable amplification, Gunn oscillation, and LSA oscillation, respectively, in Copeland´s characterization.
