Abstract

Tuning knobs are becoming common in analog and RF devices for postsilicon calibration for variation tolerance and compensation. This article presents a low-cost, hardware-iterative technique based on a steepest-descent-based gradient search algorithm and demonstrates its utility in performance tuning of a 2.4-GHz transmitter system.
