Patent ID: 6972549

Claim:
A bandgap reference circuit, comprising: a first current path comprising a current input, a first diode and a first tapping node for tapping off a voltage dependent on a forward voltage of the first diode; a second current path comprising a current input, a resistor, a second diode and a second tapping node for tapping off a voltage dependent on the forward voltage of the second diode; a differential amplifier comprising a first input, which is connected to the first tapping node, a second input, which is connected to the second tapping node, a bias current input and an output, which is coupled to the current inputs of the first and second current paths and at which a signal dependent on a voltage difference at the first and second inputs is provided; and a resistance connected between the bias current input of the differential amplifier and a reference potential, and configured to provide a reference current for the differential amplifier.
