Abstract
A reference voltage generation circuit for a plurality of reference generation voltages and a pipe line analog-to-digital converter (ADC) using the same are provided. The reference voltage generation circuit including a charging capacitor for stabilizing the reference voltages charges the charging capacitor prior to the generation of the reference voltages, thus decreasing the time for the pipe line ADC to operate stably.
