摘要：

A novel generalized impedance converter topology realized using current feedback operational amplifiers is introduced in this paper. The main offered benefit, in comparison to the corresponding already published structure, is that frequency dependent negative resistors can now be also realized. Other benefits are the requirement for only grounded capacitors, the lower component count, and the capability of tuning through a grounded resistor. The correct operation of the proposed GIC has been verified through a design example, where a 3rd-order lowpass filter has been topologically simulated. (C) 2007 Elsevier GmbH. All rights reserved.
