Abstract
A transceiver for ADSL systems contains an interpolated combfilter, halfband filters, oversampling sigma delta modulator, a current steering DAC and an analog filler. The circuit complexity of the architecture makes it necessary to use behavioral models to determine the system features. For this reason, we need a specific behavioral simulation environment using the Matlab program. The Matlab is crucial for these circuits to be rapidly incorporated in larger systems, in particular in the context of mixed-signal-test schemes. Design trade-off among the blocks has also been discussed. The design methodology is based on behavioral design and CMOS process.
