Stability-improved Non-Foster Inductance based on Compensated Passive Structure

A concept of negative (non-Foster) inductance with very robust stability properties is proposed. Proposed device is based on compensated passive RC structure and it is very convenient for microelectronic realization since it does not contain any inductor. Basic idea is verified by realistic circuit simulations of negative inductance designed for operation in UHF band. Foreseen applications are in active metamaterial/metasurface structures.
