Abstract
A folded reference voltage flash analog-to-digital (ADC) converter and a method thereof are provided. The flash ADC of the present invention determines the most significant bit (MSB) of an analog input signal, varies a reference voltage input to a plurality of comparators in accordance with the MSB determination result, and determines the remaining bits. Accordingly, input capacitance can be reduced while maintaining the size and power consumption of the ADC.
