13 RFPAL Key Architectural Attributes Analog (RF & BB), Digital (high & low-speed) and SW partitioning minimize power & area Computation of correction terms in digital (software and hardware) domain Application of correction in the analog domain RF and most of baseband analog circuitry is unclocked enables robustness and flexibility for various modulation schemes & carrier frequencies. Flexible Work Function Synthesizes wide range of PA AM/AM and AM/PM compensation and memory compensation (1ns - 300ns) Enables robust adaptation (orthogonal basis terms of work function) Robust performance with process, voltage, aging and temperature variations Extensive digital/analog compensation loops for analog cells, with process/temp sensing, calibration routines, etc. Optimized calibration algorithms using a low-power, on-chip spectral estimator. Software-driven analog circuit design that can be conveniently tuned /optimized. Software-driven correction enables flexibility With respect to waveforms, PA, power consumption (duty-cycle), etc. Allows customization of solutions by application and customer 13
