Abstract

A reference current generating circuit includes a positive temperature coefficient current source configured to generate a first current, a value of which increases with an increase of an ambient temperature thereof, a negative temperature coefficient current source configured to generate a second current, a value of which decreases with the increase of the ambient temperature thereof, a first current adjustment circuit configured to adjust the first current in accordance with a first adjustment setting value, to thereby generate a positive temperature characteristic current, a second current adjustment circuit configured to adjust the second current in accordance with a second adjustment setting value, to thereby generate a negative temperature characteristic current, and a current amplifier configured to amplify a combined current of the positive temperature characteristic current and the negative temperature characteristic current, to thereby generate a reference current.
