摘要 |
An embodied ADC includes a sampling unit sampling differential input signal to output differential sampled signal which has first and second sampled signals. The ADC includes a reference signal generator generating first and second reference signals and a preamplifier amplifying the differential sampled signal to output a differential amplification signal having first and second amplified outputs. The preamplifier has a first differential amplifier amplifying the first sampled signal using the first reference signal and a second differential amplifier amplifying the second sampled signal using the second reference signal. The ADC includes a comparator comparing the first and second amplified outputs and a correction controller controlling common-mode voltage levels of the first and second reference signals or common-mode voltage levels of the first and second sampled signals in accordance with the operations of the first and second differential amplifiers. |
