Circuit Realization of Impedance Loading for Cross Section Reduction
Edward Lawrence McMahon · Deep Blue (University of Michigan) · 1970
Techniques for realizing a reactance which is a decreasing function of frequency are discussed. A Negative Impedance Converter (NIC) circuit is analyzed and techniques given for compensating for imperfections and frequency dependence. An RC realization of the desired impedance is given, and it is demonstrated that this realization can be modified to compensate for phase shift in the NIC. An analytical and numerical analysis of a NIC based on amplifiers with 50 ohm input and output impedances is presented.
