Suitability of passive RC-network-based inductorless bridged-T as a bandpass NGD circuit

Purpose The purpose of this paper is to study, a bridged-T topology with inductorless passive network used as bandpass (BP) negative group delay (NGD) function. Design/methodology/approach BP NGD under study composed an resistive capacitive network. circuit analysis elaborated from the equivalent impedance matrix. Then, analytical model C-shunt voltage transfer function established. considered developed in parameters. properties and characterizations proposed are analytically expressed. Moreover, relevance theory verified design fabrication surface mounted device components-based proof-of-concept (PoC). Findings From measurement results, −151 ns at center frequency 1 MHz over −6.6 dB attenuation very good agreement PoC. Originality/value This develops mathematical modeling circuit.
