Originální abstrakt

The paper describes design of the bandpass sigma-delta modulator (BP SDM), which is used for conversion of the output signal from the capacitive pressure sensor. This approach is absolutely new and unique, because this kind of modulators is utilized especially for wireless applications. The main advantage of the BP SDM for sensor signal processing is its immunity against in-circuits offsets. The paper shows basic ideas of this approach and simulation results with ideal and real modulator. The main stages are implemented in switched-capacitor (SC) technique. The modulator layout is presented as well.
