Abstract
A multi-bit resolution sub-pipeline structure for measuring a jump magnitude of a transmission curve, comprising: a sub-analog-to-digital converter having n-bit resolution configured to quantize input analog voltage signals and output digital voltage signals; a sub-digital-to-analog converter having n-bit resolution configured to convert the digital voltage signals output by the sub-analog-to-digital converter into corresponding analog voltage signals; a decoder having n-bit resolution configured to decode an n-bit binary input signal; and a switched-capacitor amplification unit configured to, when in a normal mode, perform sampling and residue amplification on the input analog voltage signals; and when in a test mode, measure the jump magnitude of the transmission curve corresponding to each decision level. Magnitude measurement of a transmission curve is performed within 2clock periods, th and a measurement result is sent to a back-end digital domain of the A/D converter for correction.
