Distributed CMOS Bidirectional Amplifiers

This book describes methods to design distributed amplifiers useful for performing circuit functions such as duplexing, paraphrase amplification, phase shifting power splitting and power combiner applications. A CMOS bidirectional distributed amplifier is presented that combines for the first time device-level with circuit-level linearization, suppressing the third-order intermodulation distortion. It is implemented in 0.13µm RF CMOS technology for use in highly linear, low-cost UWB Radio-over-Fiber communication systems.

• Describes CMOS distributed amplifiers for optoelectronic applications such as Radio-over-Fiber systems, base station transceivers and picocells;
• Presents most recent techniques for linearization of CMOS distributed amplifiers;
• Includes coverage of CMOS I-V transconductors, as well as CMOS on-chip inductor integration and modeling;
• Includes circuit applications for UWB Radio-over-Fiber networks.
