Latest Patents

Yamamoto is credited with 1 patent, titled “Current Detection Circuit.” The invention includes detection terminals and an output circuit that produces a signal indicating the voltage drop between them. An amplifier strengthens that signal, and an analog-to-digital conversion circuit samples it at a predetermined cycle to generate a digital signal.

The circuit also uses a filter to extract noise components with frequencies higher than the converter’s sampling frequency. A comparison unit identifies when the filtered output exceeds a reference value, signaling a noise-detection timing. Based on that comparison signal, an arithmetic circuit delays the sampling timing by a predetermined interval. This approach is intended to reduce the effect of high-frequency noise on sampled measurements.
