Abstract
Bandgap circuit for generating a temperature-independent reference voltage, including a diode-resistance path at which a temperature-independent reference voltage corresponding to the energy gap of semiconductor material of components used in the circuit is available, the diode-resistance path including a diode and a series circuit of at least two resistors being connected in parallel with the diode, a temperature-independent reference voltage which is independent of the energy gap of the semiconductor material being available at one of the resistors.
