Abstract :
Analog front-end electronics for wireless and digital communications systems encompass a broad range of functions such as LNA, down-mixer, IF amp, up-mixer, TX amp, AGC, filters and ADC/DAC, etc. Depending on system configurations and requirements, performance and design criteria also vary. This work aims to give an insight into critical analog design issues from the system perspectives. Topics to be discussed are RF isolation issues in integrating a whole system on a CMOS single die, an ADC architecture for software radio, and a low-voltage ADC technique for 1V single battery operation
