ABSTRACT:
An improved band-gap voltage reference apparatus and method is detailed that incorporates an amplifier to provide for improved compensation and temperature stability to the voltage reference circuit by increasing the effective hFE(also called β) of the bipolar junction transistors (BJTs) used in the band-gap voltage reference circuit. This also allows the band-gap voltage reference circuit to operated with a lower overall power usage and with lower supply voltages. Additionally, the improved band-gap voltage reference apparatus and method also allows for band-gap voltage references to be implemented in integrated circuit technologies that do not have high quality BJTs natively available in the manufacturing process of the technology.
