In this paper we present an analog electronic interface, developed in an integrated standard CMOS technology, for differential capacitive sensors. In particular, the two cases of hyperbolic and linear capacitive behavior have been considered. The capacitive evaluation can be done by the design and characterization of a suitable electronic circuit which determines the measurand variations through the...
In this paper we propose a low single supply voltage (2V) analog lock-in amplifier, completely integrable on silicon, designed in a standard CMOS technology, for electronic sensor interfaces used in low-frequency applications. In particular, the proposed architecture is suitable for those sensor interfaces where the signal to be measured has a small amplitude and is buried into noise. In these cases,...
An integrated temperature sensor, operating with low voltage supply in the temperature range of 0-100??C, is here presented. The working principle is based on the fact that two different currents flowing into bipolar transistors produce a ??Vbe proportional to the absolute temperature. Two low voltage operational amplifiers with low input offset voltage make, the whole structure able to work with...
