Latest Patents

Masaaki Katoh holds a patent for a signal detection circuit for optical disks. This invention involves a comparator that converts an analog high-frequency (HF) signal into a digital HF signal using a slice level. The circuit includes a dropout detection mechanism that identifies any dropouts in the digital HF signal. Additionally, a charge-pump circuit provides feedback to the comparator based on the dropout detection results. The design also features a voltage follower that holds and outputs a voltage stored in a capacitor. When a dropout signal is detected, a switch is turned OFF, allowing the voltage follower to output the stored voltage. A second switch is activated to apply the output of the voltage follower to the comparator during dropout detection.
