Abstract
The paper presents results obtained after theoretical investigating and mathematical modelling a radio-engineering device for forming signals based on a bipolar transistor structure with negative resistance. A new equation for approximating the static I–V curve of the bipolar transistor structure with negative resistance was proposed. A simple analogue circuit of the radio-engineering device for forming signals was considered. A mathematical model of the device was suggested. Dynamics of the periodic oscillation was examined in modes of amplification, frequency division, and input signal amplitude modulation. Phase portraits, Lissajous curves, time diagrams, amplitude-frequency spectra of input and output voltages were obtained.
