of the previous SICOFIs will be omitted. This is a benefit for
the user but it makes a very high demand on the analog circuitry.
ADC and DAC are changed to Sigma-Delta-concepts to fulfill the stringent requirements
on the dynamic parameters.
Using 1
μ
m CMOS does not only lend to problems – it is the only acceptable solution in
terms of area and power consumption for the integration of more then two SICOFI
channels on a single chip.
It is rather pointless to implement 2 codec-filter-channels on one chip with pure analog
circuitry. The use of a DSP-concept (the SICOFI and the SICOFI-2-approach) for this
function seems to be a must for an adequate two channel architecture.
