A multistage analog-to-digital data conversion, including: a first stage unit configured to process an analog input signal into a first number of most significant bits using a first reference signal, and to output a first stage residue signal; a second stage unit configured to receive and process the first stage residue signal into a second number of remaining least significant bits using a second reference signal; a sampling unit configured to sample the first stage residue signal received from the first stage unit onto the second stage unit with a passive element; and an output unit configured to output a digital value that is a combination of the first number of most significant bits and the second number of remaining least significant bits. |
