Circuit arrangement for temperature compensation voltage or current reference value generation from supply voltage, comprises reference value monitoring circuit (203) formed in such that a current or voltage is generated

摘要

The circuit arrangement comprises a proportional to absolute temperature (PTAT) circuit (201) for generating a PTAT signal (I1), which is proportional to the absolute temperature. A complementary to absolute temperature (CTAT) circuit (202) for generating a CTAT signal (UBE), which is in reverse proportional to the absolute temperature. A reference value monitoring circuit (203) is formed in such a way, that a current (I2) or a voltage is generated in the CTAT circuit or in the PTAT circuit to generate the reference value monitoring signal (UREF-OK).
