Journal ArticleDOI
Active Microwave Circuit With Negative Group Delay
TL;DR: In this paper, the design, simulation and implementation of an active negative group delay circuit that operates at 1 GHz with a group delay and a gain, respectively, around 2 ns and 2 dB.
Journal ArticleDOI
Similitude between the NGD function and filter gain behaviours
TL;DR: The introduced transform relationships simplify the synthesis of any NGD circuits from simple elementary low-pass NGD topologies, and the possibility of the ultra-wideband pulse signals propagating in time-advance is verified.
Journal ArticleDOI

Pinki Punia,Manish Kumar Bharti,Sonia Chalia,Rakesh Dhar,Blaise Ravelo,Preeti Thakur,Atul Thakur +6 more
TL;DR: A detailed review of the various synthesis and characterization techniques for the production of the nanoparticles can be found in this paper, where the authors highlight the unlimited potential of nanoparticles and their derivatives in the domain of contaminated and wastewater treatment.
Proceedings ArticleDOI
Synthesis of Broadband Negative Group Delay Active Circuits
TL;DR: In this paper, the design and synthesis of active circuits able to simultaneously produce negative group delay and gain at microwave frequencies or for baseband signals is discussed, and a synthesis approach is extracted and applied to design a two-stage microwave circuit, further validated by experimental results.
Journal ArticleDOI
Theory of Coupled Line Coupler-Based Negative Group Delay Microwave Circuit
TL;DR: In this article, a fundamental theory of coupled line coupler-based negative group delay (NGD) topology is established, which consists of the isolated-and coupled-accesses connected in a feedback loop through a lossy interconnect line.
