Latest Patents

One of his latest innovations is a jitter cancellation circuit. This circuit includes a clock buffer and a current control unit. The clock buffer inputs a clock outputted from a clock propagation element driven by a power supply voltage. Furthermore, the clock buffer decreases with respect to a power supply voltage according to an increase in an operating current, while giving a delay time increased according to a decrease in the operating current to output the clock. The current control unit is designed to increase or decrease the operating current of the clock buffer in an opposite phase of the fluctuation component of the power supply voltage. Another notable patent is a semiconductor device that features a phase interpolation circuit. This circuit includes an N-bit current digital-analog conversion circuit, a switch circuit, a capacitive element, an inverter, and a control logic circuit. The control logic circuit detects the end of a phase interpolation operation by using the output result of the inverter and outputs a first control signal for turning off the current digital-analog conversion circuit. Additionally, it detects the end of the phase interpolation operation by using the output result of the inverter and outputs a second control signal for turning off the inverter.
