Abstract
A reference voltage generator includes a proportional to absolute temperature (PTAT) current source and a voltage divider. The PTAT current source is capable of providing a first current that is proportional to a temperature. The voltage divider is capable of receiving a second current that is proportional to the first current. The voltage divider is capable of outputting a reference voltage. The reference voltage is substantially independent from a change of the temperature.
