The application today, pushing analog design for CMOS and RF-bipolar i
nto new frontiers is definitely the mobile radio telephony. New teleco
m systems like GSM, PCN, DECT, DCS, Wireless in the loop... are all de
veloping very rapidly and will enable us very soon to organise a compl
ete telephone network with full coverage for your car, as well as in y
our kitchen and on your office desk. In Europe the major telecom compa
nies have worked together to establish one common standard for cellula
r mobile radio communications at 900 MHz. Similar things are happening
for other wireless personal communication systems. Basically the cell
ular radio telephone, the wireless PABX and the wireless SLIC are brin
ging the same challenges to analog circuit design: maximum integration
of the basic radio functions into 1 or 2 silicon chips, CMOS, Bipolar
or BiCMOS or GaAs. The analog circuit designer for radio telephone ap
plications will need all the state of the art analog design know-how a
vailable today, from RF-mixers and GHz range low noise amplifiers and
local oscillator synthesizers over base band 100 kHz CMOS analog to lo
w frequency speech analog to digital conversion. And for all these cir
cuits the message is: minimum power consumption for battery autonomy,
minimum silicon area for maximum functional integration per die to obt
ain a small, low cost pocket size radio telephone.
