System-level power modeling and estimation is a non-trivial task for the architecture and power management strategies exploration during early design phases of a cellular LTE modem. It requires system architects to consider not only highly heterogeneous SoC architectures, but also various worldwide LTE network configurations and dynamic scheduling which impact modem power consumption significantly...
The frequency-domain testing of analog and radio-frequency integrated circuits usually requires full-blown discrete Fourier transform (DFT) engines for spectrum analysis. However, the built-in spectrum analysis is prohibited due to the excessive computation requirement. This brief proposes a novel built-in frequency-domain testing algorithm based on quadrature sampling, which allows the evaluation...
