The Multistandard Challenge
Accommodating multiple standards in a monolithic radio-frequency (RF) transceiver
tends to signifi cantly increase the circuit complexity in both the RF and baseband
portions, resulting in a lower integration and a higher power consumption. The
transition from single-standard to multistandard is nontrivial. It requires a complete
reconsideration of the RF front-end and baseband circuitries. At the time of this
writing, the successful implementation of a high-quility multistandard RF IC is
widely regarded as one of the most challenging design tasks.
One notable challenge lie ...
