Design of Mixed Signal Circuits and Systems for Wireless Applications

چکیده
The wireless communication systems design plays the important roles in the field of microelectronics and system-on-chip methodologies. Traditional digital, mixed signal and analog low-frequency designers have enjoyed an integrated front-to-back IC design system. On the other hand, radio frequency or microwave designers with a discrete design background have used board-level computer-aided design (CAD) tools. The objective of this paper is to present some results of research work in the field of RF analog and mixed signal wireless communication systems design. We also discuss the challenges facing microelectronics in modern wireless communications systems. Analog and mixed signal design methodologies and simulation problems as well as modern CAD tools for mixed signal circuits and systems are discussed.

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
متن کاملAn Efficient Technique for Substrate Coupling Parasitic Extraction with Application to RF/Microwave Spiral Inductors (RESEARCH NOTE)
This paper presents an efficient modeling method, based on the microstrip lines theory, for the coupling between a substrate backplane and a device contact. We derive simple closed-form formulas for rapid extraction of substrate parasitics. We use these formulas to model spiral inductors as important substrate-noise sources in mixed-signal systems. The proposed model is verified for the freque...
