Inductors are bulky and costly but reducing the size of the inductors reduces the quality factor. There is also a fundamental limitation of using inductor that it cannot be suitable for the micro miniature structure and integrated circuits applications. Because of these limitations, inductors cannot be used in most of the analog circuit applications. Hence simulated inductors are used as an alternative. In case the simulated inductor becomes floating some linear transformation is used which results in the formation of a new D element called the Frequency Dependent Negative Resistance (FDNR). This paper presents an overview of the basic circuits of simulating the Frequency Dependent Negative Resistance and its various applications in analog circuits in the place of floating inductor.
