Abstract
A current mode A/D converter for reducing current consumption while enhancing resolution. The A/D converter includes a V/I conversion circuit for sampling and converting an input voltage to a current, an I/V conversion circuit for converting the current supplied from the V/I conversion circuit to a comparison voltage, a comparator for comparing the current based on the comparison voltage and a reference current, and an encoder for generating a digital output signal based on the output signal of the comparator.
