NEGATIVE-RESISTANCE DEVICE Russian patent published in 1997 - IPC

FIELD: radio engineering, can be used as an active component in self-sustained oscillators, active filters, amplifiers, nonlinear compensators, pulse-forming devices. SUBSTANCE: negative- resistance device, using transistors 1-8 and current generators 15-18, has also bipolar element 9 with internal impedance, amplifier element 10, diode two-terminal networks 11-14 and current generator 19, which makes it possible to eliminate the dependence of negative resistance on emitter resistances of transistors 1,3 and an additional adjustment of negative resistance due to variation of the number of diodes in diode two-terminal networks 11-14. EFFECT: improved quality. 3 cl, 2 dwg
