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.
