N2 - This paper presents a design of transmission-type arbitrary terminated negative group delay (NGD) circuit with constant signal attenuation (SA). In the proposed circuit, the specified NGD and SA response can be designed by handling the characteristic impedance of transmission lines. Analytical analysis disseminates that the input and output ports of the proposed NGD circuit can perfectly match at a center frequency (f0) without extra matching networks. The proposed analytical equations can also apply to design an arbitrary terminated absorptive bandstop filter with prescribed NGD. For an experimental confirmation, a prototype of the transmission-type NGD circuit was at the f0 of 2.14 GHz. The experimental results are consistent with simulated and analytical results.
