Abstract:
An apparatus and method for a voltage reference circuit with flexible and adjustable voltage settings. A voltage reference circuit, comprising a PTAT Current Generator configured to provide current through a first resistor, a CTAT Current Generator configured to provide a CTAT current through a second resistor, a PTAT-CTAT Adder circuit configured to sum the PTAT current, and the CTAT current, wherein said sum of the PTAT and CTAT current through a third resistor is configured to provide an output voltage greater than a silicon bandgap voltage.
