The proposed structure is used to provide superior stopband to suppress the simultaneous switching noise (SSN) coupling within typical power/ground planes. The MV-GSPL is periodically distributed metal patches shorting to the continuous ground plane and can be embedded in a coplanar type EBG structure to enhance its stopband. This structure is able to provide almost 140 fractional bandwidth without any additional component in a compact unit cell area. An efficient 1-D analysis model is also proposed. The 1-D model is able to consider the via effect of MV-GSPL on the stopband. In the application aspect, a test C-band low noise amplifier (LNA) fabricated by the TSMC 0.18um 1P6M process is packaged on the LPC-EBG with MV-GSPL substrate for noise immunity test. Both the chip-package co-simulation and experimental results show excellent power noise isolation capability of the RF package for the C-band LNA. The proposed EBG structure is confirmed possessing up to 50 % spurious noise reduction in output spectrum of the LNA.Chapter 1 Introduction 1.1 Research Motivations 1.2 Simultaneous Switching Noises (SSNs) in Power Distribution Networks 2.3 SSN Coupling in Mixed-Signal Systems 5.4 Proposed Research and Dissertation Outline 6hapter 2 Literature Survey for Solving SSN Coupling 8.1 Power Plane Segmentation 8.2 Discrete and Embedded Decoupling Capacitor 9.3 Electromagnetic Bandgap Structure 10.3.1 Mushroom Type EBG Structure 11.3.2 Coplanar Type EBG Structure 16.3.3 Photonic Crystal Type EBG structure 19.4 Summary 20hapter 3 LPC- EBG Structure with Multiple Via Ground Surface Perturbation Lattice for Stopband Enhancement 21.1 Design Concept of LPC-EBG with MV-GSPL 21.2 Proposed One Dimensional Equivalent Circuit Model 26.2.1 ABCD Matrix and Periodic Boundary Condition (PBC) 26.2.2 Proposed One Dimensional Equivalent Circuit 31.3 Fabrication and Measurements 42.4 Parameter Analysis 46.5 Summary 50hapter 4 Application Study for EBG Power/Ground Planes in Mixed Signal System 52.1 A Low Noise Amplifier in a Mixed-signal System 53.2 Design and Fabrication of Power Distribution Networks (PDN) 56.3 Power Integrity Analysis of PDN 59.4 Measurement Results of LNA under SSN coupling 66.5 Summary 71hapter 5 Conclusion 72eference 733330110 bytesapplication/pdfen-US接地彈跳雜訊(Simultaneous Switching Noise)電磁能係結構(Electromagnetic Bandgap Structure)混合信號系統(mixed-signal system)simultaneous switching noise(SSN)Electromagnetic bandgap (EBG)mixed-signal systemthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/188281/1/ntu-98-R96942013-1.pdf
