Abstract
A balanced voltage reference circuit has a transistor that is operated as an emitter follower and to whose base two resistors are connected in series for beta compensation of the balanced circuit. One end of the smaller resistor which faces away from a transistor base, the smaller resistor being split into two resistor elements, is connected inside the chip to a signal point of an amplifier circuit whose operating point can be adjusted. In which case, one end of an integrated capacitance is connected, as a parallel element of an RC filter, between the two resistor elements of the smaller resistor.
