Abstract
An integrated circuit, including: a bias current circuit including a first resistor, the bias current circuit being configured to generate a first bias current, based on the first resistor and a reference voltage; a second resistor to which the first bias current is supplied; n diodes to which a second bias current is supplied, the n diodes being connected in series, the serially-connected diodes having a first node on a power supply side thereof and a second node on a ground side thereof; and a compensation circuit configured to apply a compensation voltage corresponding to a voltage generated at the second resistor, to the second node. The n is an integer equal to one or more. A temperature coefficient of the second resistor and a temperature coefficient of the first resistor are either one of positive or negative.
