Design Considerations for an Automotive Sensor Interface Sigma-Delta Modulator
(Institute of Electrical and Electronics Engineers, 2003)
The Sigma-Delta Modulator presented in this paper contains a programmable-gain input inferface to accommodate the output signal level of a variety of automotive sensors. We show that this characteristic can be efficiently ...

Expandible high-order cascade ya modulator with constant, reduced systematic loss of resolution
(Institute of Electrical and Electronics Engineers, 2003)
An arbitrary order sigma-delta modulator cascude architecture is presented with only I-bit loss of resolution due to scaling issues, even with single-bit quantizulion. This loss is kept with a high overloading point, ...

BandPass Sigma-Delta Analog-to-Digital Converters
(Springer, 2003)
The principle of ΣΔ Modulation (ΣΔM) is extended in BPΣΔMs to bandpass signals, especially but not only, with a narrow bandwidth. Thus, BPΣΔMs have much in common with their lowpass counterparts - whose properties have ...
