Abstract:
A temperature compensation circuit, comprising:a first transistor having an emitter coupled to a first power conductor and a collector for conducting a temperature compensated output current; a second transistor having an emitter directly connected to a base of the first transistor, an emitter coupled through a first current source to the first power conductor, and a collector coupled to a second power conductor; a third transistor having a base and a collector coupled through a second current source to the second power conductor, and an emitter coupled to the base of the second transistor; a fourth transistor having a base coupled to the base of the third transistor, an emitter coupled through a third current source to the first power conductor, and a collector coupled to the second power conductor; a fifth transistor having a base coupled to the emitter of the fourth transistor, an emitter coupled through a fourth current source to the first power conductor, and a collector coupled to the second power conductor; and a sixth transistor having a base coupled to an emitter of the fifth transistor, a collector coupled to the emitter of the third transistor, and an emitter coupled to the first power conductor.
