Description	Článek popisuje novou kalibrační techniku, která je použita v 10-bitovém řetězovém převodníku DA. Převodník pracuje v technice spínaných kapacitorů. Protože je převodník určen pro aplikace s bateriovým napájením, byla uvažována i potřeba co nejmenší spotřeby obvodu. Spolu s novou kalibrační technikou byly použity modifikované obvodové techniky, které dohromady řeší problémy spojené s technikou SC. (cs) The article describes a new background calibration technique, which is used in a new 10-bit low power pipelined ADC. The switched-capacitor approach (SC) is utilized in proposed ADC as well. The low power consumption is one of the most important issues considered in the design, because the ADC is intended for using in portable applications. Well-known operational-amplifier (op-amp) sharing technique was modified and used to decrease the power usage. The capacitor scaling approach is suitable for the same purpose. The basic problems coupled to SC, such as clock feedthrough from digital part through the switches, capacitor mismatch and op-amp non-idealities, have been taken into account during a design of the ADC. These error sources are canceled or roughly attenuated by means of novel background calibration or using known analog-domain techniques. The special op-amps and comparators were designed for this purpose. The power consumption of the op-amps was taken into account, too.
