Abstract
An analog-to-digital conversion circuit is provided. A voltage divider of the analog-to-digital conversion circuit regulates a voltage range received by a sample holder of analog-to-digital conversion circuit. Accordingly, a first half of the sample holder can use an electrical device with a low operating voltage. Since an operation speed of the electrical device with the low voltage is faster than an electrical device with a high operating voltage, an operation frequency of the sample holder can be raised.
