Abstract
The electronic circuit for measuring at least one physical parameter supplies an analogue output measurement signal (S) dependent upon the value of a supply voltage. The circuit includes a sensor interface, connected to a sensor for supplying an analogue measurement signal (V) which is then filtered, an analogue-digital converter for digitally converting the filtered signal (S), and a digital signal control and processing unit for receiving a converted signal from the converter and supplying a digital measurement signal (S). The sensor interface, the analogue-digital converter, and the processing unit are powered by a voltage regulator. The analogue and digital measurement signals are thus independent of any variation in the supply voltage (V) of the electronic circuit. A ratiometric unit, which may be an analogue multiplier or an analogue-digital converter, is powered by the supply voltage source (Bat) to recreate ratiometry on Son the basis of Sor S.
