Novel behavioral DAC modeling technique for WirelessHD system specification

A new DAC behavioral model for system-level simulations is introduced. After presenting the most critical DAC parameters, the proposed modeling technique is described. It takes into account both the static and dynamic limitations of the DAC component while being close the circuit architecture. The impacts of the DAC dynamic impairments are then studied at the system-level for the WirelessHD standard. In such wideband systems, the impact of the DAC is critical. Lastly, it is shown that this model can be used to compare different DAC architectures at the EVM level.
