A Simple Grounded FDNR Based-on CDTRA and Its Application for a Sinusoidal Oscillator
Main Article Content
Abstract
This article proposes a simple grounded Frequency Dependent Negative Resistance (FDNR) based on CDTRA cooperating with 4 floating passive elements. The features of the proposed circuit are that; the impedance can be controlled by passive devices. Moreover, the circuit is theoretically temperature-insensitive which is preferable for using in a temperature control/measurement work. It is suitable for further fabricating in the IC architecture. The application example as a sinusoidal oscillator is included. The simulation results using PSpice are given for the introduced grounded simulator to verify the theory and to exhibit the performances of the circuit.
