Title:
Stabilizing methods for current source
Abstract:
A stabilizing method for a current source is provided. The current source is provided a current which increases when temperature rises. An adjustment circuit provides an input current increasing when temperature rises. A rising ratio of the input current with temperature is the same as a rising ratio of the current of the current source with temperature. The current of the current source is subtracted from the input current. After the current of the current source is subtracted from the input current, the current of the current source does not vary when temperature varies.
