20130257635 | DIGITAL CORRECTION CIRCUIT FOR A PIPELINED ANALOG-TO-DIGITAL CONVERTER - A digital correction circuit for a pipelined analog-to-digital converter (ADC) is disclosed. Compared to the conventional digital correction circuit which uses adders to perform operations in ADC digital correction part and hence needs a rather long operation time, the digital correction circuit of this invention can reduce the time needed in operations in the finial digital correction circuits and thus can optimize operation time, by allocating the operations to a plurality of pipeline stages of second sub-circuits configured to synchronize digital codes, each of which can perform part of the operations only with NAND gates, NOR gates, phase inverters and D-type flip-flops, without needing to use adders. | 10-03-2013 |
20140320323 | PIPELINE ANALOG-TO-DIGITAL CONVERTER - A pipeline analog-to-digital converter is disclosed which includes at least one periodic unit consisting of two adjacent stages that jointly use two capacitor networks of the same structure. Each of the capacitor networks includes two identical capacitors, two switches and four terminals. On/off states of the switches and interconnection configuration of the terminals are controlled by clock signals to switch the periodic unit between four possible connection configurations. During operation of the periodic unit, when the upstream stage is in a sampling phase that involves one of the capacitor networks as well as a reference capacitor, the downstream stage uses the other of the capacitor networks to conduct residue amplification; and on the other hand, when the upstream stage is using one of the capacitor networks for residue amplification, the downstream stage relies also on this capacitor network for sampling, leaving the other of the capacitor networks idle. | 10-30-2014 |
