ABSTRACT

This paper presents novel low-voltage all-MOS analog circuit techniques for the synthesis of oversampling ΣΔ A/D converters. The new approach exploits the possibilities of Log-domain processing by using the MOSFET in subthreshold operation. Based on this strategy, a complete set of very low-voltage (down to 1 V) low-power (below 100 μW) all-MOS basic building blocks is proposed. The resulting analog circuit techniques allow the integration of ΣΔ A/D converters for low-frequency (below 100 KHz) applications in digital CMOS technologies. Examples are given for a standard 0.35 μm VLSI process.
