This paper is concerned with an investigation of the negative resistance parametric oscillator. As with all nonlinear reactances the voltage variable capacitor, most commonly used in parametric emplifiers can be made to exhibit a negative resistance under certain circuit configuration. This negative resistance effect can be made to result in oscillatory condition in the output of the device.
