Reference voltage generating circuit using active resistance device |
摘要 |
A reference voltage generating circuit includes a current mirror circuit having first and second current paths formed between a first power source terminal and a second power source terminal in which the current mirror circuit is operated in response to a voltage level of the second current path, a reference voltage output node for providing a reference voltage and being located on the second current path, an active resistance device formed on the first current path to be operated in a linear region of a current-voltage characteristic curve of the active resistance device, and a voltage supply circuit for supplying the active resistance device with an enable voltage to control the active resistance device to be operated in the linear region.
