Abstract
An effective means and apparatus for generating a negative resistance including a circuit element that exhibits an increase in current as the applied voltage is decreased. Other embodiments of the present invention provide electronic means for improving the quality Q factor of on-chip resonators, which enables the creation of high-performance bipolar RF circuits with a minimum of external components.
