Polar radio architectures are attractive due to the ability to implement them using largely digital architectures. However, testing for specs such as EVM incurs significant test time due to the large numbers of symbols that need to be transmitted. In our approach, EVM is modeled as a function of the system static non-idealities (IQ mismatch, gain, IIP3 parameters) and dynamic non-idealities (VCO phase...
Polar radio architectures are gaining in popularity due to the promise of an all digital implementations in future CMOS systems-on-chip (SoCs) solutions. Test cost is an important consideration for manufacturers developing these complex devices. Phase noise is an important specification in all digital polar radios as it affects the signal modulation quality. In this paper, a low cost test technique...
