Latest Patents

One of Saitoh's latest patents is a "Clock data recovery circuit." This invention utilizes multiple flip-flops that each latch input data at a specific time point of the corresponding clock signal. The i-th first logical gate generates an internal up signal when the output of the (2·i−1)-th flip-flop does not match the output of the (2·i)-th flip-flop. Additionally, the j-th second logical gate generates an internal down signal when the output of the (2·j)-th flip-flop does not match the output of the (2·j+1)-th flip-flop. A third logical gate generates an up signal based on the multiple internal up signals, while a fourth logical gate generates a down signal based on the multiple internal down signals.

Another significant patent is for a "Control circuit and control method for charge pump circuit." This invention provides a charge pump circuit that includes a voltage/current conversion circuit. This circuit compares a feedback voltage corresponding to the output voltage of the charge pump with a predetermined reference voltage, generating a bias current that corresponds to the difference. An oscillator then oscillates at a frequency that corresponds to the bias current, while a buffer, biased by the bias current, supplies a gate clock to the charge pump circuit based on a clock signal output from the oscillator.
