Title: Toshiaki Kurokawa: Innovator in AD Converter Technology
Introduction
Toshiaki Kurokawa is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of analog-to-digital converters, holding a total of 4 patents. His work focuses on enhancing the performance and efficiency of AD converters, which are crucial in various electronic applications.
Latest Patents
One of Kurokawa's latest inventions is a time-interleaved AD converter. This innovative device combines low-speed high-resolution AD converters to achieve effective high-speed operation. It addresses various deterioration factors, such as DC offset and conversion gain error, through nonlinear filter operations. By adding a constant term to the linear filter operation, the device compensates for these issues without being affected by quantization noise from a high-speed low-resolution AD converter.
Another significant patent is his predistortion amplifier. Unlike traditional digital predistortion compensation devices that rely on absolute value information, Kurokawa's invention calculates distortion compensation using a complex coefficient polynomial. This method utilizes the real and imaginary parts of the baseband complex input signal as variables, leading to more accurate compensation.
Career Highlights
Throughout his career, Toshiaki Kurokawa has worked with prominent companies, including Hitachi, Ltd. and Hitachi Communication Technologies, Ltd. His experience in these organizations has allowed him to develop and refine his innovative ideas in the field of electronics.
