A flash analog to digital converter includes a voltage generator circuit, an encoder circuit, and first and second double differential amplifier circuits. The voltage generator circuit generates reference voltages according to first and second voltages. The encoder circuit generates a digital signal corresponding to an input signal according to first signals. The first double differential amplifier circuit compares the input signal with a first reference voltage in the reference voltages, to generate a corresponding one of the first signals. The second double differential amplifier circuit compares the input signal with a second reference voltage in the reference voltages, to generate a corresponding one of the first signals. A difference between the first voltage and the first reference voltage is less than that between the first voltage and the second reference voltage, and the first and the second double differential amplifier circuits have different circuit architectures.
