ABSTRACT:
A fast power-on band-gap reference circuit includes a buffer, a first band-gap logic, and a second high drive band-gap logic. During power-on of the band-gap reference circuit, both the first band-gap logic and the second high drive band-gap logic are activated, in which the first band-gap logic charges an output of the first band-gap logic and the second high drive band-gap logic charges a capacitance associated with an output of the band-gap reference circuit. When the output of the first band-gap logic reaches a predetermined value, the second high drive band-gap logic is deactivated and the output of the first band-gap logic is couple to the output of the band-gap reference circuit through the buffer.
