Abstract
Embodiments of a voltage reference circuit are described. In one embodiment, a voltage reference circuit includes a startup circuit configured to generate a startup current and to be turned off in response to a comparison between the startup current and a current threshold, an amplifier connected to the startup circuit and configured to generate an amplified current using a positive current feedback loop in response to the startup current, and a proportional to absolute temperature (PTAT) current generator configured to generate a temperature-independent reference voltage in response to the startup current and the amplified current. Other embodiments are also described.
