摘要：

In this paper, a high-Q floating active inductor (FAI), suitable for RF and microwave applications, is presented. The proposed FAI is based on two cascaded pairs of highly linear capacitance gyrators, which provide a symmetric and reciprocal structure. The proposed FAI shows fully symmetrical two-port characteristics, high quality factor and high linearity. As a feasibility demonstration, a prototype of the designed FAI has been fabricated, together with an LC series band-pass filter. At the operating frequency, the real part of the impedance of the equivalent FAI is very low (Req=0.0039 Omega), providing a very high quality factor. The filter has a central frequency of 430MHz and a -3dB bandwidth of about 9MHz. Copyright (c) 2014 John Wiley & Sons, Ltd.
