Abstract
An analog-to-digital converter includes a reference voltage generator for dividing a voltage between first and second reference voltages by a plurality of resistors serially connected therebetween and providing a plurality of reference voltages at each connecting point of the resistors; a plurality of emitter-coupled comparators for respectively generating a comparative signal by comparing the reference voltages with an analog input signal; and a plurality of constant current sources for respectively supplying an input bias current to each reference voltage input terminal of the emitter-coupled comparators.
