SYNTHESIS OF NEGATIVE GROUP DELAY CIRCUITS

Deals with negative group delay phenomena in linear electric networks. The physically realizable transfer functions of second-order are considered for conditions of negative group delay. The formulae for negative group delay cut-off angular frequency are developed. The synthesis algorithm for the generation of active circuits with negative group delay is proposed. The algorithm is based on Generalized Parameter Extraction Method. The ARLC-circuit is derived for every considered transfer function of second-order with negative group delay. The parametric synthesis, as well as numerical modelling, are included. Excellent agreement between obtained results and LTspice XVII computation is found.
