Trade-off between antialiasing filter and analog-to-digital converters specifications in homodyne radio frequency receivers

Résumé

Base-band building blocks are critical components in radio receivers based on direct conversion architectures. Homodyne receivers can perform digital channel filtering, thus allowing a simple multi-standard channel selection implementation. The drawback of this scheme is the severe ADC requirements on dynamic range and linearity. In spite of this, those requirements can be relaxed if the antialiasing filter attenuates significantly in-band interferers. This paper presents a method that allows one to find a double trade-off between: filter complexity and converter complexity, ADC linearity and ADC resolution, verified for GSM, DECT and UMTS standards.
