发明名称 BUFFER CIRCUIT AND SEMICONDUCTOR INTEGRATED CIRCUIT
摘要 A buffer circuit section receives an input clock, and outputs an output clock by wave-shaping the input clock, a measurement circuit section measures a first pulse width at a first potential level of the output clock and a second pulse width at a second potential level of the output clock, and an adjustment circuit section adjusts a ratio between the first pulse width and the second pulse width by varying a drive capability of the buffer circuit section on the basis of the measurement result of the measurement circuit section.

主权项 1. A buffer circuit comprising: a buffer circuit section which receives an input clock, and outputs an output clock by wave-shaping the input clock; a measurement circuit section which measures a first pulse width at a first potential level of the output clock and a second pulse width at a second potential level of the output clock; and an adjustment circuit section which adjusts a ratio between the first pulse width and the second pulse width by varying a drive capability of the buffer circuit section on the basis of a measurement result of the measurement circuit section.
