Abstract
Introduction. The circuit simulation programs that are currently in use do not have tunnel diodes macro-models in their standard libraries. So it is important to create and examine a circuit diagram of tunnel diode macro-model, because tunnel diodes are often used for oscillators and amplifiers developing. Theoretical statement. The tunnel diodes macro-models are based on current / voltage characteristics that correspond to the real static characteristics and parameters. The static current/voltage characteristic of the device is defined by coordinates in characteristic points and contains a region of negative dynamic resistance. The suggested circuit diagram of tunnel diode macro-model consists of two parallel circuits. One of them forms so called λ-diode, and the other represents diode with parasitic capacitance. Conclusions. The tunnel diode macro-model was created. A set of equations for parameter computation of micro-models of different types were derived. The oscillator simulation with using created tunnel diode macro-model shows availability of adopted simulating principles.
