Title: Innovations of Shinichiro Sano
Introduction
Shinichiro Sano is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of optical transmission systems and signal processing. With a total of 2 patents, his work has enhanced the performance and stability of various technologies.
Latest Patents
One of his latest patents is a modulation controlling circuit. This invention relates to a modulation controlling circuit that supplies a modulating signal to an external modulator, which outputs a modulated optical signal. By setting a proper operating point in the external modulator, this invention enables high-quality modulation across a wide bit rate range. Consequently, the characteristics and performance of optical transmission systems or measuring instruments utilizing this invention are improved, ensuring stable operation without losing the advantages of the external modulator.
Another significant patent by Sano is an equalizing amplifier, along with a receiver and preamplifier that utilize the same technology. This equalizing amplifier equalizes an electric signal obtained from a light signal received via an optical transmission path. An automatic gain control (AGC) circuit generates first and second signals from the electric signal by referring to a threshold voltage. The offset compensation circuit generates a first difference signal based on the difference between the first and second signals, which are complementary. This innovation allows for the threshold voltage to be varied, ensuring it is centered within the amplitude of the electric signal, thus compensating for any offset in the AGC circuit.
