Abstract
An analog-to-digital converter (ADC) includes an input circuit configured to receive a first analog signal output from a first sensor or a second analog signal output from a second sensor according to an operation mode and a bit stream; a filter configured to filter an output signal from the input circuit; a quantization circuit configured to generate the bit stream from an output signal of the filter; and a digital circuit configured to generate a first digital signal corresponding to the first analog signal or a second digital signal corresponding to the second analog signal by filtering the bit stream, wherein the operation mode includes a first mode selecting the first sensor and a second mode selecting the second sensor, and wherein the digital circuit refers to the second digital signal generated during the second mode to generate the first digital signal during the first mode.
