Bandgap reference voltage circuit for generating atemperature-compensated reference voltage

摘要

pA voltage Vreg is controlled which is led off from the distribution voltage by a controlled voltage divider. The voltage Vreg is at a higher potential than the reference voltage Vref. An essential portion of the circuit layout is formed by resistors the conductivity of which decreases with rising temperature. These resistors are each connected into one voltage divider, the voltage divider point (A, B) of which remains connected with the input of a differential amplifier (K)./p [DE19620181C1]
