Abstract
An integrated circuit is provided, which includes a first voltage source, a second voltage source, a first trimming circuit, and a second trimming circuit. The first voltage source is configured to generate a first voltage which monotonically decreases with an absolute temperature of the integrated circuit. The second voltage source is configured to generate a second voltage which monotonically increases with the absolute temperature. The first and second voltages are compensated to generate a reference voltage. The first trimming circuit includes trimming devices arranged in parallel to the first voltage source, and adjusts the first voltage using the trimming devices to reduce a temperature coefficient of the reference voltage. The second trimming circuit is configured to multiply the reference voltage by a predetermined multiplication ratio to adjust an offset of the reference voltage to generate an output reference voltage at an output terminal of the integrated circuit.
