Latest Patents

Yokoi's latest patents include a clock generator and an inverter output circuit. The clock generator invention saves buffer memory for data transfer interfaces when using a spectrum spread clock in circuits and devices. This innovation allows for easy application as the operational clock in a system, thereby enhancing overall performance. The variable delay circuit in the clock generator controls the phase of the reference clock generated by an oscillator. The delay setting circuit can vary the control voltage at each clock cycle, modulating the phase of the reference clock. This phase modulation spreads the spectrum and ensures synchronization within a specified range.

The inverter output circuit comprises three inverters connected in series. The low-potential output of the first inverter has an offset level, and the input threshold voltage of the second inverter is set lower than this offset. This design prevents erratic operations of connected loads during power shutdowns or brownouts, ensuring reliability in various conditions.
