Abstract

This paper presents a simple electronic circuit which provides negative group delay (NGD). The proposed circuit is built around the current-feedback operational-amplifier and uses grounded resistors and capacitors. The proposed circuit has a high input impedance and a low output impedance. Thus, obtaining relatively long NGDs is feasible by cascading several circuits. Experimental and simulation results that confirm the functionality of the proposed circuit are included.
