Abstract:
A current reference circuit and a semiconductor IC including the current reference circuit, the current reference circuit including a proportional to absolute temperature (PTAT) current generator configured to generate, in an output branch, a first current proportional to a temperature; and a current subtractor configured to generate a reference current by subtracting a second current generated based on a current flowing in an internal branch of the PTAT current generator, from the first current flowing in the output branch. The second current is set to have a same temperature-based change characteristic as the first current and a level different from a level of the first current.

Claim (Index 12):
A current reference circuit comprising:\n a current generator including a first branch circuit, a second branch circuit, an output branch circuit and an amplifier; and a current subtractor, wherein the current generator generates a first current that is applied to the current subtractor through the output branch circuit, the first current being proportional to a temperature, the current subtractor generates a second current based on a third current that flows in an internal branch of the current generator, and generates a reference current by subtracting the second current from the first current, the reference current is insensitive to the temperature, and the amplifier amplifies a voltage difference between a node of a branch of the first branch circuit and a node of a branch of the second branch circuit, and supplies an output voltage to the first branch circuit and the second branch circuit.
