The compensation of the ohmic and the material dielectric losses in a barium strontium titanate (BST) capacitor using an active circuit is reported in this letter. The negative resistance (NR) circuit creates an effective conductance of — | Gn| which adds to the positive conductance of the passive BST-based tuned capacitor. As a result, the compensation of the losses is significantly improved in the hybrid circuit by more than 50%. To our knowledge, this is the first work in tunable BST capacitor loss compensation using a NR circuit ever reported.
