Abstract
An A/D converter having high accuracy and high throughput irrespective of characteristic variations of analog circuits is provided. The A/D converter includes a voltage-to-time converter configured to synchronize with a sampling clock signal and convert an input analog voltage to a time difference between two signals, and a plurality of time-to-digital converters each configured to convert the time difference between the two signals to a digital value. The plurality of time-to-digital converters operate in an interleaved manner.
