DSP Driven Parallel EVM Testing of Embedded MIMO-OFDM RF Modules

A self-tuning architecture for buck converters based on alternative test

“…Adaptation to process variations is also a key issue in other systems such as low-power RF & wireline systems [9][10][11]. In this context, techniques such as self-learning based adaptation [12][13], power-conscious tuning [14] and system level testing and tuning [15][16][17] concepts have been developed. Although a self-tuning approach based on alternative built-in self-test for RF devices has been developed in the past to reduce testing cost and testing time [18][19][20][21], the work reported in this paper develops, for the first time, a testing and self-tuning methodology that avoids the hazards (voltage spikes) associated with standard testing procedures while providing guarantees for the same.…”
