The design of delta-sigma modulators for multi-standard RF receivers

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-��m CMOS process. The post-layout simulation results
have verified the outcomes of system analysis. / Graduation date: 2004
