Abstract

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.
