Automatic phase alignment for a fully integrated Cartesian feedback power amplifier system.

Automatic phase alignment for a fully integrated Cartesian feedback power amplifier system.

A phase-alignment system is used in the first reported IC to fully integrate a power amplifier, Cartesian feedback linearization circuitry, and a phase-alignment system. The phase-alignment system consumes 8.8 mW from a 2.5-V supply and employs a new technique for offset-free analog multiplication t...
