Abstract

The autodyne sensor operation modelling was carried out. Authors took into account frequency dependence of the field transistor parameters. The shape and a spectrum of generated oscillations in control points of the autodyne sensor circuit were researched, depending on position of an operating point of the transistor. It is revealed, that a condition of the least distortion of the generated oscillations shape is position of a working point of the transistor in the region of camber of its transfer characteristic. Modelling was carried out with Micro-Cap application.
