Latest Patents

One of Ghannouchi's latest patents is the "Adaptive predistortion device and method using digital receiver." This advanced device utilizes digital receiver technology to improve power amplifier linearization. It performs instantaneous characterization of the power amplifier using two digital receivers, which supply dynamic AM-AM and AM-PM transfer functions. These functions are used to create Look-Up Tables (LUT) that implement a complex predistortion function, effectively compensating for non-linearity and memory effects.

Another notable patent is the "Adaptive linearization of a feedforward amplifier by complex gain stabilization of the error amplifier." This invention involves a feedforward amplifier that amplifies an input signal to produce an output signal. It generates an error signal that represents distortion in the output. The adaptive linearization circuit processes this error signal through a series of interconnected components to cancel distortion in the amplified output signal.
