Abstract
An integrated circuit includes a first temperature-sensitive device configured to generate a first voltage, a second temperature-sensitive device configured to generate a second voltage, and an output terminal configured to generate a reference voltage which is a summation of the first voltage and the second voltage. The first voltage monotonically increases with an absolute temperature. The second voltage monotonically decreases with the absolute temperature. In the integrated circuit, a low-dropout regulator has a first input connected to the output terminal and an output connected to the gate of a power regulating transistor. The channel of the power regulating transistor is connected between a first terminal configured to receive a first supply voltage and a second terminal configured to generate a second supply voltage.
