Abstract or Summary
  • The transition from second-generation (2G) to third-generation (3G) wireless cellular and cordless telephone systems requires multi-standard adaptability in a single RF receiver equipment. An important answer to this request is the use of Delta-Sigma modulators for IF-to-baseband conversion, which will satisfy the dynamic range requirements for digital signal processing, and at the same time, add adaptability and programmability to the characteristics of a RF receiver. This thesis addresses the issues of designing a Delta-Sigma modulator for a multi-standard wireless receiver. A single-loop third-order modulator topology suitable for low power and high integration multi-standard receiver design is proposed. The trade-offs in the modulator design are also presented and explained. The modulator, which has been implemented as a part of a monolithic receiver chip, will be fabricated in a standard 0.35-μm CMOS process. The post-layout simulation results have verified the outcomes of system analysis.
