Latest Patents

Paulo holds a patent for a "Method of linearizing a non-linear amplifier, linearization circuit." This invention focuses on a linearization circuit for a non-linear amplifier that optimizes overall efficiency to exceed 50%. The amplifier operates in class 'E' or class 'F' and near saturation, which leads to phase and amplitude non-linearity. Conventional methods correct phase non-linearity using a feedback loop, while amplitude non-linearity is addressed by manipulating the power supply modulator in an open loop configuration. Further refinement is achieved through an automatic gain control amplifier, which adjusts based on an amplitude error signal generated in a feedback loop.
