Abstract
An analog-to-digital converter (ADC) system, such as a subranging ADC, including a cascade of buffer circuits and signal processing circuitry to measure and cancel the distortion introduced by the buffer circuits. Thus, buffer circuits can be added to the signal path of an input signal without the detrimental effects, such as added distortion, that typically accompany the addition of buffers.
