Abstract
A voltage detecting device and an analog-to-digital converter (ADC) using the same are provided. The voltage detecting device determines whether input voltage is higher than threshold voltage based on contact of a strip and a membrane. Therefore, high resolution and high speed operation is possible, but with consuming lower power, and an element capable of performing the function of resistor and comparator is provided. Furthermore, a more effective ADC may be provided using the above.
