ABSTRACT:
A method of and apparatus for high speed, high resolution, time-shift two-step analog-to-digital conversion (ADC) employing only one ADC module for both coarse and fine signal conversions. The same ADC module is used first for the coarse signal conversion with its output signal stored until the ADC completes the slower fine signal conversion to generate the conversion error for the subsequent compensation process. A digital signal is then generated after the two signals are processed by using a digital signal processing to compensate for conversion error.
