Application of Negative Resistance in the Inductor Feedback Oscillators Based on Multisim

Abstract:

By analyzing three-point oscillator of inductance feedback with the loss resistance of the inductor,we found the loss resistance of the inductor is a major factor in affecting circuit performance. Negative resistance in series with loss resistance can offset the impact of the loss resistance in the circuit. Oscillation circuit Start-up easilier. The quality factor Q increases and the selectivity is better.The oscillation shape closer to the ideal oscillator.
