SEMICONDUCTOR DEVICE

Document Type and Number:

Japanese Patent JP2023174194

Kind Code:

A

Abstract:

To provide a small-area semiconductor device including a phase interpolation circuit which can operate at high speed.SOLUTION: A semiconductor device comprises a phase interpolation circuit including an N-bit current digital-to-analog conversion circuit, a switch circuit, a capacitive element, an inverter, and a control logic circuit. The control logic circuit detects termination of a phase interpolation operation using output results of the inverter, and outputs a first control signal which turns off the current digital-to-analog conversion circuit. In addition, the control logic circuit detects termination of a phase interpolation operation using the output results of the inverter, and outputs a second control signal which turns off the inverter.SELECTED DRAWING: Figure 3
