摘要:
An electronic circuit for generating an output voltage has a defined temperature dependence, a bandgap circuit for generating a defined temperature-constant voltage and a temperature-dependent current with a defined temperature dependence, and a conversion circuit for generating the output voltage from the temperature-dependent current and the temperature-constant voltage. The conversion circuit has a first resistor at whose first terminal the temperature-constant voltage is applied, and whose second terminal is connected to a first terminal of a second resistor. The second terminal of the second resistor is connected to a supply voltage potential, and a first terminal of a third resistor is connected to the second terminal of the first resistor. The temperature-dependent current is supplied to a second terminal of the third resistor, and it being possible to tap the output voltage at the second terminal of the third resistor.
