Temperature detecting circuit
Abstract:
A temperature detecting circuit is provided. The temperature detecting circuit includes a band gap voltage generating circuit and an offset adjusting circuit. The band gap voltage generating circuit generates a reference voltage according to a bias voltage. The band gap voltage generating circuit has a voltage dividing circuit, and the voltage dividing circuit divides the reference voltage to generate a plurality of output voltages. The offset adjusting circuit includes a current source and a resistor string. The current source provides a reference current. The resistor string receives the reference current and generates a plurality of adjusted output voltage accordingly. At least one of a current value of the reference current and a resistance of each of the resistor units is provided to be adjusted to force a voltage on an output terminal of the current source to be substantially equal to one of the reference voltage and the output voltages.
