“…It is noteworthy that the main difference is the fact that the filter is characterized from TF magnitude and the NGD is characterized from the TF group delay (GD). Based on the NGD-filter analogy, the innovative classification of low-pass (LP) [13][14][15][16][17], highpass (HP) [13][14][18][19][20][21], bandpass (BP) [4][5][6][7][8][9][10][11][12][13][14] and stopband (SB) [13][14][21][22][23] NGD topologies are identified. These different NGD topology types are characterized from the frequency band(s) where the GD is susceptible to be negative.…”

The miniaturization and application development are the expected challenges on the today engineering design research on bandpass (BP) type negative group delay (NGD) circuit. To overcome this technical limit, an innovative contribution on integrated circuit (IC) design method of BP-NGD application to design constant phase shifter (PS) in 130-nm BiCMOS technology is developed in the present paper. The BP-NGD PS microwave passive IC is topologically consisted of cascade of CLC-and RLC-resonant networks. After the S-matrix modelling, the synthesis design equations enabling to calculate each lumped component values constituting the BP-NGD PS BiCMOS are established. The design equations are expressed knowing the targeted specifications as phase shift and operating frequency. The BiCMOS design methodology including the key steps as design rule checking (DRC), layout versus schematic (LVS) and post-layout simulation (PLS) is described. The miniaturized BP-NGD PS design feasibility is verified with schematic and layout simulations with IC CMOS standard commercial software tool. A proof-of-concept (POC) of 130-nm BiCMOS BP-NGD PS operating at the center frequency f0=1.9 GHz and bandwidth ∆f=0.1 GHz is designed and simulated. After DRC, the chip layout of miniaturized BP-NGD PS POC presents 0.407 mm² size. The BP-NGD PS POC exhibits constant phase shift notable value of about φ0=-90°+/-0.4° under S21(f0)=-6+/-1 dB transmission coefficient with good flatness and reflection coefficients (S21(f0) and S21(f0)) widely better than -10 dB. The design robustness is confirmed by 1000-trial Monte Carlo uncertainty analyses with PLS results. Because of the potential integration in wireless sensor networks (WSNs), the BP-NGD PS under study is a promising candidate for the improvement of the future 5G and 6G transceiver design.

“…To answer such curious questions, simpler and more fundamental circuit theory enabling to understand the different types of NGD function is necessary. An NGD circuit theory on low-pass (LP), high-pass (HP), and bandpass (BP) using NGD elementary functions was introduced [44][45][46][47][48][49][50][51][52][53][54]. Design approaches of LP NGD type passive circuit were proposed [44][45][46][47][48][49][50].…”

“…The BP NGD type approaches notably with RF and microwave topologies [27-38, 44-47, 51] are the most expanded NGD functions. In addition, uncommon characterization of other types as HP NGD function [52,53] and stop-band NGD function [54,55] circuits wwa recently introduced. But today, the analogy between the different types of filters and the NGD concept is still not clear enough for non-specialist electronic design and fabrication engineers.…”

This paper investigates the design method, characterization, and innovative uncertainty analysis of bandpass (BP) type negative group delay (NGD) passive cell. The lumped passive topology under study consists of a resistor and a passive RLC-series network. The voltage transfer function (VTF) based circuit theory introducing the BP NGD specification analytical expressions is established in function of the R, L, and C lumped component parameters. The BP NGD performance is evaluated by figure of merit (FOM) formula. To demonstrate the BP NGD function, the design method was applied to a proof-of-concept (POC) operating at 125-kHz RFID standard center frequency. The BP NGD theory is validated by both AC simulation and measurement of POC and discrete component-based circuit prototype. Experimental BP NGD results in good agreement with calculation and simulation are obtained with NGD value of −36.77 µs, 8% NGD bandwidth, and an attenuation lower than −9.6 dB. Innovative expressions of BP NGD parameter uncertainties are established versus the POC circuit parameters. The BP NGD specification variations are interpreted with respect to the influence of constituting component uncertainties via comparison between the established NGD uncertainty theory and co-simulated sensitivity analyses.

This paper investigates on the theorization, design, fabrication and measurement of original phase shifter (PS) operating with two-step stair phase behavior. The innovative stair PS is designed with unfamiliar stop-band (SB) negative group delay (NGD) passive circuit. The elementary unfamiliar SB-NGD topology constituted by resistive, inductive, and capacitive lumped network is described. Acting as an RF and microwave circuit, the S-matrix model is expressed in function the RLC-network parameters. Thus, the canonical form of unfamiliar SB-NGD transfer function (TF) represented by the transmission coefficient is established. The unfamiliar SB-NGD circuit equations in terms of the NGD parameters are formulated. The established theory is validated comparing the calculated, simulated, and measured S-parameters and group delays (GDs). Results with a very good agreement showing unfamiliar SB-NGD behavior are observed around the central frequency 2.45 GHz and bandwidth of 100 MHz. An innovative application of unfamiliar SB-NGD function for the communication system front-end is developed. The developed application concept of unfamiliar SB-NGD circuit is illustrated by designing a microwave device operating as a PS presenting a two-step stair response completely original behavior. The basic theory, design and implementation of the two-step stair PS concept are introduced. To validate the two-step stair PS principle, a proof of concept (PoC) is designed based distributed element based inductive and capacitive microstrip elements. The simulated and measured results of the PS PoC are in good agreement. The experimental results confirm the feasibility of two-step stair PS with phase jumping from −70 • ±4 • (from 2 GHz to 2.3 GHz) to −104 • ±2 • (from 2.6 GHz to 3.0 GHz). The investigated unfamiliar SB-NGD function-based stair PS is promising for future development 5G and 6G communication system.INDEX TERMS Circuit theory, innovative concept, design method, microwave circuit, passive topology, Sparameter model, stop-band (SB) negative group delay (NGD), SB-NGD application, stair phase shifter (PS).
