Temperature compensation circuit

A temperature compensation circuit comprising:

• a first transistor having a control terminal supplied with a first signal;
• a first resistor having a first end connected to an output of the first transistor;
• a second transistor having a control terminal supplied with a second signal;
• a second resistor having a first end connected to an output of the second transistor;
• a third resistor having a first end connected to a first connection point to which a second end of the first resistor and a second end of the second resistor are commonly connected;
• a constant voltage element connected to the third resistor;
• a third transistor having a control terminal connected to the first end of the first resistor;
• a fourth transistor having a control terminal connected to the first end of the second resistor;
• a fifth transistor having a control terminal supplied with the first signal;
• a first control circuit having a first input terminal connected to an output of the fifth transistor and supplied with a first current outputted from the fifth transistor, a second input terminal connected to a fourth resistor wherein a second current flows through the second input terminal, and an output terminal outputting a third current depending on a difference between a value of the first current and a value of the second current;
• a sixth transistor having a control terminal supplied with the third current;
• a seventh transistor having a control terminal which is connected to the control terminal of the sixth transistor, is supplied with the third current, and outputs a current depending on the third current to a second connection point to which the fourth and fifth transistors are commonly connected;
• an eighth transistor having a control terminal connected to the control terminal of the sixth transistor;
• a first mirror circuit connected to the eiqhth transistor;
• and
• a second mirror circuit connected to the first mirror circuit.
