IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 24(3), 1151–1164.

author keywords: Calibration; digitally reconfigurable radio frequency integrated circuits (RFICs); Hooke-Jeeves algorithm; Nelder-Mead algorithm; self-healing
TL;DR: It is shown that the proposed hybrid Nelder-Mead and Hooke-Jeeves calibration algorithm is capable of reducing the gain error and phase error of the phase rotator output to less than a maximum of 0.5 dB and 2° relative to the chosen gain and phase targets. (via Semantic Scholar)

A Bounded and Discretized Nelder-Mead Algorithm Suitable for RFIC Calibration

IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS I-REGULAR PAPERS, 60(7), 1787–1799.

By: E. Wyers n, M. Steer n, C. Kelley n & P. Franzon n

author keywords: Calibration; derivative-free optimization; Nelder-Mead direct search algorithm; PLL spurious tone reduction; radio frequency integrated circuit calibration
TL;DR: It is shown that a gradient descent-based algorithm has difficulty in reducing the VCO control line ripple, while the proposed algorithm reduces the relative power of the first harmonic reference spurs by at least 10 dBc and effectively enables design complexity reduction in the supporting analog calibration circuitry.
