| Description
| - Tento příspěvek pojednává o nové postkalibrační metodě, která koriguje některé chyby, které vznikají převodem v řetězovém převodníku AD (ADC) při použití obvodové techniky spínaných kapacitorů (SC). Spolu s některými modifikovanými obvodovými principy pak komplexně řeší problémy, které s technikou SC souvisejí. Samotný návrh řetězového ADC byl ovlivněn několika požadavky, a to zejména nízkou spotřebou (pro použití v přenosných zařízeních), dobrým rozlišením při vysoké rychlosti převodu, vysokou linearitou převodu a odolností vůči parazitním vlivům jako jsou různé druhy šumů, parazitní kapacity apod. (cs)
- The paper deals with a novel 12-bit low power switchedcapacitor (SC) pipelined analog-to-digital converter (ADC). The problems caused by using of SC technique are compensated or roughly attenuated by means of combination of well-known analog-domain techniques and new digital background calibration technique. Since portable applications demand for low power consumption, it is one of the most important issues considered in the design. A modified operational-amplifier (op-amp) sharing technique was used to decrease the power usage as well as capacitor scaling approach. To avoid the clock feedthrough from digital part through the switches the fully differential circuitry was utilized. The special op-amps and comparators were designed for this purpose and to obtain large bandwidth. The power consumption of the op-amps was taken into account too. The finite op-amp dc gain problem is solved in digital-domain using background calibration. The capacitor mismatch and op-amp offset are compensa
