Abstract
A device that generates a DC reference voltage approximately equal to half a DC supply voltage. It includes an input stage forming a first potentiometric divider comprising two branches having an asymmetric behavior in response to variations in the room and/or operating temperature, and supplying a first DC voltage (NBGP), an intermediate stage forming a resistive and capacitive filter, which eliminates the dynamic component of the first DC voltage (NGBP) and supplies a second DC voltage (NARF), and an output stage forming a second potentiometric divider comprising two branches also having an asymmetric behavior of which the voltage variations are smaller than those of the first divider comprising in addition a logic inverter function, and supplying a third DC voltage (NREF), the variations of which are the inverse of those in the second DC voltage (NARF), the variations in the latter being thus compensated.
