Review on Variable and Programmable Gain Amplifiers and Applications

Variable and programmable gain amplifiers have been a recurrent subject of study over the last 50 years, and, are increasingly used in different applications today. This work presents an overview of these amplifiers as to serve as an up-to-date source of information for studies and designs. Different architectures and techniques are presented and classified for both radio and intermediate frequencies, since there are major differences in the requirements according to bandwidth. Typical applications where VGAs and PGAs are employed are also presented.

期刊介绍： This journal will present state-of-art papers on Integrated Circuits and Systems. It is an effort of both Brazilian Microelectronics Society - SBMicro and Brazilian Computer Society - SBC to create a new scientific journal covering Process and Materials, Device and Characterization, Design, Test and CAD of Integrated Circuits and Systems. The Journal of Integrated Circuits and Systems is published through Special Issues on subjects to be defined by the Editorial Board. Special issues will publish selected papers from both Brazilian Societies annual conferences, SBCCI - Symposium on Integrated Circuits and Systems and SBMicro - Symposium on Microelectronics Technology and Devices.
