Latest Patents

Watanabe's latest patents include a phase coincidence detector and a power-saving intermittently operated phase-locked loop. The phase coincidence detector is designed to examine whether two input digital signals are coincident by utilizing delay and advance signals from a digital phase comparator. This invention effectively changes the delay and advance signals through a pulse width discrimination circuit, allowing for accurate output of in-phase and out-of-phase states. The power-saving intermittently operated phase-locked loop aims to stabilize the oscillator frequency during the power-on phase by detecting the point in time when the phase difference between clock signals becomes substantially zero. This innovation ensures that the frequency dividers are initialized correctly, preventing significant frequency changes.
