Abstract
In this paper, we introduce a new frequency compensation method of the CCII based floating inductance. In order to get tunable characteristics of the proposed inductance, a translinear CCII is implemented for its controllable series parasitic resistance at port X. After achieving a frequency characterization of the proposed CCII, we analyze the frequency limitations of the conventional CCII based tunable floating simulated inductance which is independent of tuning current. To overcome these limitations, a pole/zero compensation strategy is applied. Therefore, a series passive resistance Rs=650Q is used and a high active negative resistance is introduced by means of CCII's. Simulation results show that the proposed compensation technique enlarges the tuning range of the inductance. Moreover, a special arrangement is proposed so that the compensation solution is insensitive to the control current tuning the inductance value.
