Abstract :
A phase alignment system is used in an IC that fully integrates a 14.2dBm PA, Cartesian feedback, and phase-alignment circuitry. The alignment system consumes 8.5mW from a 2.5V supply, uses a 2GHz carrier, and rejects phase disturbances over a 180/spl deg/ range. The IC was fabricated in a 0.25/spl mu/m CMOS process.
