Abstract
An integrated circuit includes a first temperature-sensitive device having a first stacked gate device formed and a second stacked gate device, and a second temperature-sensitive device having a third stacked gate device. The first temperature-sensitive device is configured to generate a first voltage which monotonically increases with an absolute temperature. The second temperature-sensitive device is configured to generate a second voltage which monotonically decreases with the absolute temperature. The integrated circuit also includes an output terminal configured to generate a reference voltage which is based on the first voltage from the first temperature-sensitive device and the second voltage from the second temperature-sensitive device. Each of the first stacked gate device, the second stacked gate device, and the third stacked gate device is formed with a first group of field-effect transistors stacked together.
