Abstract
A semiconductor device includes: a voltage-control-type clock generation circuit having a plurality of stages of first delay elements and whose oscillation frequency is controlled according to a control voltage applied to the first delay elements; a delay circuit having a plurality of stages of second delay elements connected serially; and a selection circuit selecting one from pulse signals output by the plurality of stages of respective second delay elements. The first delay elements and the second delay elements have a same structure formed on a same semiconductor substrate, and a delay amount of the second delay elements is adjusted according to the control voltage.
