Abstract
An A-D conversion circuit configured to convert an analog input signal into numerical data using a pulse delay circuit includes pulse position digitizing units, a clock generation circuit, and a processing unit. The clock generation circuit includes inverters each including one or more n-channel transistors and one or more p-channel transistors. The inverters differ from each other in a number ratio of the number of n-channel transistors connected in a common-gate parallel-connected manner and the number of p-channel transistors connected in a common-gate parallel-connected manner.
