Supply Induced Aperture Uncertainty-Aware Target Impedance Methodology to Solve RFIC Receiver Design Challenge Based On PDN Analysis

Chip-package-System co-design has been attracting attention recently as a design methodology in development. One of the most important elements is to present detailed analysis of supply induced aperture uncertainty of RFIC receiver analog front-end for signoff in frequency domain. With aperture uncertainty sensitivity extraction of RFIC receiver analog front-end block circuit (LNA/Mixer/DC offset cancellation/VGA/bandwidth filter/level shifter), it is possible to enable accurate aperture uncertainty-aware target impedance calculation. The goal during system-level design is to provide adequate performance at minimum cost while giving the in-depth SI/PI insight into RF analog front-end design field and achieving on system-level success.
