Architectures and circuits for RF CMOS receivers

This paper presents recent work in receiver architectures and circuits for RF CMOS applications. First, receiver topologies such as heterodyne, direct-conversion, and image-reject configurations together with their trade-offs are described. Next, the design of building blocks, e.g., low-noise amplifiers and mixers, baseband interfaces, and oscillators is studied. Three design examples for ISM, DECT, and cellular applications are then reviewed and unresolved issues in RF CMOS design are summarized.
