Latest Patents

Among his latest patents is a semiconductor integrated circuit device and a method for evaluating an eye-opening margin. This innovative method measures the eye-opening margin for high-speed serial data reception circuits. It utilizes a clock data recovery circuit that operates without fixing the clock phase. The method allows for error acceleration testing on received data by introducing an offset pulse signal to the phase information, adding a jitter component. The semiconductor integrated circuit device includes a serializer/deserializer circuit (SerDes) for receiving serial data and a reference serializer/deserializer circuit (Ref_SerDes) for the accompanying clock signal. The SerDes circuit converts the received serial data into parallel data through a recovery clock, with its phase controlled by a phase control signal generated by the Ref_SerDes circuit.

Another notable patent focuses on reducing the error rate of a bit synchronous circuit. This is achieved by preventing excessive following of jitters present in the input data. The phase detect circuit of the bit synchronous circuit incorporates a majority decision circuit that counts signals as a phase comparison result. This circuit outputs signals based on the majority count, effectively reducing the error rate for bit synchronization.
