The structure of a new OTA floating inductance simulator is given. It is simple and can be realized very easily. Its most advantage is that the volume of the inductor can be adjusted continuously by changing the bias current IABC. The curcuit given in this paper can be made with the monolithic integrated circuit. A kind of Caure low-pass filter is realized by using this kind of floating inductor and it is shown that the experimental results are in good agreement with the theoretical design.
