Description	Článek popisuje novou architekturu převodníku sigma-delta vyššího řádu pro senzorové měření. Převodník s dvoustupňovým kvantovacím procesem je využit jako vícebitový kvantovací obvod.Prezentována acrhitektura byla namodelována v prostředí Matlab Simulink.V modelu 16-bitového sigma-delta modulátoru jsou zahrnuty parazitní vlivy, které se u sigma-delta modulátorů objevují. (cs) This paper presents a novel architecture of highorder single-stage sigma-delta (Σ∆) converter for sensor measurement. The two-step quantization technique was utilized to design a novel architecture of Σ∆ modulator. The time steps are interleaved to achieve resolution improvement without decreasing of conversion speed. This technique can be useful for low oversampling ratio. The novel architecture was designed to obtain high dynamic range of input signal, high signal-to-noise ratio and high reliability. The proposed architecture of switched-capacitor (SC) Σ∆ modulator was simulated with blocks containing nonidealities, such as sampling jitter, noise, and operational amplifier parameters (white noise, finite dc gain, finite bandwidth, slew rate and saturation voltages).
