Abstract

The following paper would like to give an idea of the present status of silicon technologies used for the analog front-end of communication systems. The frequency spectrum of application is that of the mobile communications standards (up to few GigaHertz). A short description of the available active devices (CMOS, SiGe BJT, DMOS) will be presented. In addition some information regarding the feasibility of good quality passive components (Inductors, Capacitors, Varactors, Resistors) will be given.
