Latest Patents

Kuroiwa holds a patent for a "Glitch detection circuit and method." This invention features a glitch detection circuit that includes an A/D converter, a state holding circuit, a discrimination circuit, and a storing circuit. The A/D converter samples an input signal at a predetermined sampling interval to produce digital data during a predetermined acquisition interval, which is longer than or equal to the sampling interval. The state holding circuit is connected to the output terminal of the A/D converter and holds the distribution state of the digital data during the acquisition interval. The discrimination circuit detects maximum and minimum values during the acquisition interval based on the digital data held in the state holding circuit. The storing circuit then stores these maximum and minimum values for each acquisition interval. This arrangement eliminates the need for a feedback loop that limits operation speed in conventional circuits, effectively doubling the operation speed and sampling frequency of the analog-to-digital converter. The circuit can detect glitches of a half pulse width.
