Abstract
A current generating circuit includes a first circuit subunit, a second circuit subunit and a third circuit subunit. The first circuit subunit is configured to generate a first current having a first temperature coefficient. The first temperature coefficient is a negative temperature coefficient. The second circuit subunit is configured to generate a second current having a second temperature coefficient. The second temperature coefficient is a positive temperature coefficient. The third circuit subunit is configured to generate a third current having a third temperature coefficient according to a difference between the first current and the second current. An absolute value of a slope of the third temperature coefficient is greater than that of the first temperature coefficient or that of the second temperature coefficient.
