Abstract
A current compensation circuit includes: a second bipolar transistor configured to have a same process variation as the first bipolar transistor; a first transistor including a drain connected to the emitter of the second bipolar transistor; a second transistor including a gate connected to a gate of the first transistor, and a drain connected to its own gate; a third transistor including a drain connected to the emitter of the first bipolar transistor, and a gate connected to the drain of the second transistor and each gate of the first and the second transistors; a constant current source; a fourth transistor including a drain connected to the base of the second bipolar transistor, and a gate connected to its own drain; and a fifth transistor including a drain connected to one end of the constant current source, and a gate connected to the gate of the fourth transistor.
