Temperature detection circuit

Temperature detection circuit

A temperature detection circuit (1) includes a first transistor (Q1) of a bipolar type, and a second transistor (Q2) of a bipolar type, wherein the first transistor (Q1) and the second transistor (Q2) form a current mirror circuit (10), and the temperature of the amplifier circuit (30) is detected b...

description A temperature detection circuit (1) includes a first transistor (Q1) of a bipolar type, and a second transistor (Q2) of a bipolar type, wherein the first transistor (Q1) and the second transistor (Q2) form a current mirror circuit (10), and the temperature of the amplifier circuit (30) is detected based on a temperature change of the first transistor (Q1) and the second transistor (Q2).
