Latest Patents

Fahmi's latest patents include innovative technologies that focus on signal amplification and transmission. One of his patents, titled "Signal amplification and transmission based on complex delta sigma modulator," discloses apparatuses and methods for power amplification and signal transmission using complex delta-sigma modulation. This invention features a complex delta sigma modulator unit that includes a complex polar quantizer within an integrator loop. The quantizer effectively quantizes the envelope of a complex integrated signal, producing a complex quantized output signal of substantially constant envelope. This output signal is crucial for deriving a complex feedback signal within the integrator loop, which can drive a power amplifier at saturation. Additionally, an adjacent channel power ratio (ACPR) enhancement technique is employed to minimize quantization noise.

Another significant patent is the "Level de-multiplexed delta sigma modulator based transmitter." This specification introduces a level de-multiplexed DSM-based transmitter and outlines methods for its implementation. The embodiments enable wireless transmitters that utilize multi-level de-multiplexed DSM, with a three-level de-multiplexed DSM-based transmitter provided as an example. The technology allows for enhancements in efficiency and linearity of transmitters, tailored for specific applications.
