摘要

本文的目的是研究一种无电感无源网络的桥接t拓扑作为带通(BP)负群延迟(NGD)函数。所研究的BP NGD拓扑由无电感无源电阻容性网络组成。从等效阻抗矩阵出发对电路进行了分析。然后，建立了c -并联桥- t拓扑电压传递函数的解析模型。所考虑的拓扑的BP NGD分析是在桥接- t参数的函数中发展起来的。本文对所提出的拓扑结构的NGD性质和特征进行了解析表达。此外，BP NGD理论的相关性通过基于表面贴装器件组件的概念验证(PoC)的设计和制造得到验证。从测量结果来看，中心频率为1mhz的- 151 ns BP NGD网络在- 6.6 dB衰减下与c分流桥接- t PoC非常吻合。本文提出了c -并联桥接- t网络电路的数学建模理论和测量方法。

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