Abstract
The physical parameter measurement method is performed using an electronic circuit () with a resistive sensor (). The resistive sensor includes two resistors (R, R) mounted in series, whose connection node connected to a moving mass (M), is connected to a first input of an amplifier-comparator (). A second input of the amplifier-comparator receives a reference voltage. One output of the amplifier-comparator is connected to a logic unit (), which provides a digital output signal (OUT). A digital-to-analogue converter () provides a measurement voltage (V), as a function of a digital signal provided by the logic unit, to the first resistor (R) in a first phase of a measurement cycle, whereas the second resistor (R) is polarized by a polarization voltage, and to the second resistor in a second phase, whereas the first resistor is polarized by a polarization voltage via a switching unit.
