Latest Patents

Yasutoshi Tada holds a patent for a distortion compensation circuit, a power amplifier utilizing this circuit, and a method for generating distortion compensation signals. This innovative circuit enhances compensating accuracy while reducing convergence time. It achieves this by generating a distortion compensation signal for pre-distortion with precision and speed. The circuit generates an error signal that represents the difference between the input and output signals of the power amplifier. From this error signal and the input signal, coefficients for third-order, fifth-order, and seventh-order intermodulation distortions are calculated. Based on these coefficients, a distortion compensating signal is produced, which is characteristically opposite in phase and gain to the intermodulation distortions.
