Abstract:
An analog-to-digital (A/D) conversion system comprising:a first conversion stage, having an input and an output, wherein the first conversion stage receives an input signal on the first conversion stage input, converts the input signal, and produces an output signal on the first conversion stage output; a second conversion stage, having an input and an output, wherein the second conversion stage receives the first conversion stage output on the second conversion stage input, converts the first conversion stage output signal, and produces an output signal on the second conversion stage output; a third conversion stage, having an input and an output, wherein the third conversion stage receives the second conversion stage output on the third conversion stage input, converts the second conversion stage output signal, and produces an output signal on the third conversion stage output; a fourth conversion stage, having an input land an output, wherein the fourth conversion stage receives the third conversion stage output on the fourth conversion stage input, converts the third conversion stage output signal, and produces an output signal on the fourth conversion stage output; and wherein the above steps are repeated with the fourth conversion stage output as the input signal until a desired N-bit resolution is achieved.
