- 초록
- A reference current bias circuit includes a self-bias circuit configured to provide a bias current to an amplifier; a basic bandgap circuit coupled to inputs of the amplifier; a startup circuit configured to support an initial operation of the amplifier; a temperature compensator configured to include a first mirroring unit for mirroring current according to a positive temperature coefficient characteristic from the basic bandgap circuit; and a second mirroring unit for mirroring current according to a negative temperature coefficient characteristic from the basic bandgap circuit, and to provide a reference current by combining the current of the first mirroring unit and the current of the second mirroring unit; and a reference current mirroring unit configured to generate reference current biases based on the reference current from the temperature compensator.
