Latest Patents
One of Aoki's latest patents is a method and circuit for correcting sensor temperature dependency characteristics. This innovation aims to prevent an output signal, which has been corrected through digital or analog means, from deviating from a target value. It also addresses issues related to power supply noise and power consumption. The sensor amplification circuit receives the output of a sensor as an input signal, with correction points set at predetermined temperature intervals. The circuit performs digital correction using correction data for each point and a second correction for input signals between these points, utilizing gradient data from adjacent correction points.
Another significant patent is for a MOS type variable capacitance device. This device features an n-well formed in a p-type semiconductor substrate, with a gate insulative film and a gate electrode. A source layer, selectively diffused with n-type impurities, is formed adjacent to the gate insulative film. This design allows for a capacitance characteristic of good linearity over a wide range relative to the inter-terminal voltage, making it suitable for enhancing the performance of VCO circuits. The structure is simple and can be manufactured easily without the need for additional masks and steps.
