Title: Wataru Naito: Innovator in Semiconductor Technology
Introduction
Wataru Naito is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His work focuses on enhancing the performance of radio receivers and semiconductor devices.
Latest Patents
Naito's latest patents include a radio receiver and an intermediate frequency signal generation method. This invention features an IF filter that band-limits an intermediate frequency signal outputted from a mixer. An AFC unit controls the oscillation frequency of a PLL to ensure that the frequency of the intermediate frequency signal is a predetermined frequency. The AFC unit adjusts the oscillation frequency while a band control unit manages the passing characteristic of the IF filter. After completing the control, the passing characteristic is adjusted from a wide band to a narrow band. Additionally, a frequency correction unit refers to a filter information storage unit to correct the oscillation frequency based on the difference between the center frequencies of the wide and narrow bands.
Another notable patent is a semiconductor device and method that reduces degradation of reception performance caused by an image signal. This device includes an oscillation circuit that generates a local signal, a mixer that multiplies a reception signal by the local signal, and an analog filter that processes the output from the mixer. An AD converter digitalizes the filtered signal, which is then processed by a digital filter. A power comparator detects the power difference between the first and second signals, while a register stores a theoretical power difference. A determination unit then establishes the frequency of the local signal based on the detected power difference.
