Lossy Coupling Matrix Synthesis Approach for the Realization of Negative Group Delay Response

IEEE Access, 2018
In this paper, a systematic synthesis approach is proposed for achieving negative group delay responses using lossy coupling matrix. It is mathematically proved that, for a passive and reciprocal network, loss is the necessary condition to realize a ...

The leaky integrator with recurrent inhibition as a predictor

, 2016
It is shown that the leaky integrator, the basis for many neuronal models, possesses a negative group delay when a time-delayed recurrent inhibition is added to it.

HP-NGD Circuit Theory With Generalized Exponential Kernel Fractional Derivative-Based Impedances

IEEE Access
In this work, we propose a novel passive circuit theory on fractional High-Pass (HP) Negative Group Delay (NGD) topology by using the fractional order reactive impedance and admittance.

A Compact Dual-Band Negative Group Delay Microwave Circuit [PDF]

Radioengineering, 2018
A compact dual-band negative group delay circuit (NGDC) is proposed. The proposed NGDC is composed of an open-circuited transmission line and two resistors connected by two transmission lines.
