-Several methods of realization of floating inductance with current conveyors, current feedback amplifier has been reported. The methods for the realization of inductance simulation with electronically tunable properties using current controlled conveyors required well matching of transistors. These devices have limited performance due to component matching. Simulation of inductance is also obtained from second generation current conveyors with excessive number of components. The simulated inductance is varied through passive elements and the approach is based on the use of current differencing buffer amplifier realized with CMOS technology and is unavailable in integrated form. Operational transconductance amplifier has an attractive feature of transconductance gain which is linearly controlled over more than 4 decades from the bias current. The OTA is a commercial low cost device and also easy to implement in monolithic integrated form. The realization of floating inductance simulation is more attractive. A commercial OTA with least number of active and passive elements exhibit an attractive method to simulate a floating inductance. A review on floating inductance using number of OTAs with resistor and single capacitor is reported in terms of searching for the best method of simulating the floating inductance in the design of low pass filter.
