Conception of simulating grounded negative inductor and implementation using operational transconductance amplifiers

This paper presents a novel realization of a grounded negative inductor simulator (NIS). The conception of creating grounded NIS is discussed and then a possible circuit realization using operational transconductance amplifier (OTA) is provided. The proposed circuit realization employs only two OTAs, one voltage summing circuit and three capacitors. PSPICE simulations have validated the workability of the proposed NIS in the operating frequency of 10kHz to 10MHz.
