Abstract

An analog-to-digital (AD) converter and a voltage detecting device thereof are provided. The AD converter includes at least one voltage detecting device which outputs a signal of a frequency determined based on a magnitude of an input voltage using a resonance frequency of a resonator. The AD converter determines a digital output value depending on the output signal from the voltage detecting device. Therefore, the AD converter can achieve a high resolution and a high speed with far less power consumption.
