Latest Patents

Among his latest patents is the invention titled "Dynamic assignment with phase-preserving clipping technique for digital transmitters and power amplifiers." This invention features a transmitter that includes a first digital-to-analog converter (DAC) circuit, which consists of a first set of unary cells to mix a first set of digital input data with a first clock signal. Additionally, a second DAC circuit is included, which comprises a second set of unary cells to mix a second set of digital input data with a second clock signal. A third circuit provides signals to both DAC circuits to implement an assignment scheme that assigns either an in-phase (I) component or a quadrature (Q) component to the respective sets of unary cells. This innovative approach allows for the effective handling of I-data and Q-data in digital transmission.

Another notable patent is "Systems and methods for controlling transmission of power using attenuation."
