Signal generation circuit and temperature sensor

To provide a signal generation circuit having a short settling time of an output voltage. In a PTAT signal generation circuit, a trimming circuit is coupled between the cathodes of 0-th to K-th diodes and a line of a ground voltage, the anode of the 0-th diode is coupled to a first node, the anodes...

Summary:To provide a signal generation circuit having a short settling time of an output voltage. In a PTAT signal generation circuit, a trimming circuit is coupled between the cathodes of 0-th to K-th diodes and a line of a ground voltage, the anode of the 0-th diode is coupled to a first node, the anodes of the first to the K-th diodes are coupled to a second node via a resistive element, the first node and the second node are set to the same voltage, a first current flowing through the 0-th diode and a second current flowing through the first to the K-th diodes are set to have the same value, and a third current flowing through the trimming circuit is set to have the value 2 times that of each of the first current and the second current.
