Temperature detection circuit

A temperature detection circuit comprising:

• a bandgap reference voltage generation circuit for generating a first reference voltage, the bandgap reference voltage generation circuit including a current path to produce a thermal voltage and being configured to cause a bias current to flow through the current path, the current path having a first resistor:
• a detection output circuit having a second resistor, the detection output circuit being configured to cause a mirror current of the bias current to flow through the second resistor;
• and
• an output conversion circuit that uses a second reference voltage to convert a voltage drop across the second resistor to a predetermined output form to detect a temperature,
• wherein the first and second resistors are substantially identical in temperature dependence, and
• wherein the second reference voltage is generated from the first reference voltage.
