Open circuit stable non-Foster negative inductor

This contribution proposes a band-pass non-Foster negative inductor. Its stability properties are superior to those from standard designs, including possibility of achieving overall negative inductance. Proposed band-pass negative inductor is based on Negative Impedance Converter (NIC) of Open Circuit Stable (OCS) type. Stability analysis revealed that there is inevitable trade-off between generated negative inductance and achieved operating bandwidth.
