Patent ID: 6906580

Claim:
A method of forming a reference voltage generator comprising: forming a bipolar transistor current mirror to generate an output current that is a function of both a value of a first Vbe voltage of a reference transistor of the bipolar transistor current mirror plus a value of a difference between the value of the first Vbe voltage and a value of a second Vbe voltage of a difference transistor of the bipolar transistor current mirror including coupling the reference transistor and the difference transistor to generate a reference current proportional to the first Vbe voltage of the reference transistor, coupling the difference transistor to receive a first portion of the reference current as a difference current, coupling the reference transistor to receive a second portion of the reference current as a remainder current, and coupling a Vbe resistor to the reference transistor and the difference transistor to receive the first Vbe voltage and responsively form a Vbe current to flow through the Vbe resistor as a third portion of the reference current.
