Latest Patents

One of Tetsuya Aisaka's latest patents is the "Swallow Counter with Modulus Signal Output Control." This innovative design allows PLL frequency synthesizer circuits to operate at high speeds without internal delays or malfunctions. The swallow counter supplies a modulus signal to a prescaler, which can selectively change the frequency-dividing ratio of a frequency signal. The design includes a shift register, a counter, a count-up detector, a modulus signal generator, and a control circuit. This swallow counter is capable of counting a frequency-divided signal based on set value data and producing the modulus signal in response to a load signal after counting is completed. It also determines whether the set value data is intended to fix the frequency-dividing ratio, ensuring efficient operation.
