Latest Patents

One of Dragos Cartina's latest patents is titled "Method and device for digital compensation of dynamic distortion in high-speed transmitters." This invention describes a transmitter that includes a shift register, a lookup table, and a digital-to-analog converter. The shift register is designed to receive an input signal and output delayed copies of that signal. The lookup table stores compensation values estimated based on the input signal and its delayed copies. The digital-to-analog converter then outputs a transmit signal that incorporates these compensation values to reduce distortion during the conversion process.

Another significant patent by Cartina is also focused on digital compensation of dynamic distortion. This device and method involve a digital-to-analog converter connected to a lookup table, along with two shift registers. The method iteratively adjusts input values via the lookup table to induce changes in the output of the digital-to-analog converter, compensating for dynamic distortion. This process includes capturing average output values for sequences of symbols and updating the lookup table with estimated values to eliminate clipping. The method can be combined with techniques such as equalization and amplitude scaling to enhance output signal characteristics.
