Electronic circuit, method of controlling electronic circuit, and electronic apparatus |
摘要 |
An electronic circuit includes a plurality of delay elements configured to delay a clock signal by a delay time and to supply the delayed clock signal as a delay signal, the delay time being shorter with a higher power source voltage; a delay time acquisition unit configured to acquire the delay time based on a value of the delay signal; and a voltage controller configured to perform a voltage control process in which the power source voltage is controlled to be high in a case where the acquired delay time is longer than a predetermined desired value and the power source voltage is controlled to be low in a case where the acquired delay time is shorter than the predetermined desired value. |
