Smart RFIC: Millimeter-wave gigabit transceivers with digitally-enabled built-in self-calibration and auto-switching functions: The challenge of phase control modeling in phase shifter design

摘要

This paper reviews recent digitally calibration and IQ mismatch compensation techniques. The phase control modeling of phase shifter or modulator design is the most challenging task in high-speed communications. All these built-in self-calibration and auto-switching functions are innovated to pave the road to the next-generation millimeter-wave 5G mobile smart RFIC.
