  • Abstract
    We demonstrate a truly continuous regulator of oscillator phase alignment suitable for high bandwidth Cartesian feedback power amplifiers. A new approach to the problem is introduced, which yields a simple nonlinear dynamical controller. Our prototype achieves accurate regulation (3.8 degrees) at the highest baseband bandwidth reported
