ABSTRACT:
A multi-mode band-gap current reference includes a band-gap current mode module and an adjustable current source module. The band-gap current module provides a band-gap reference current and a voltage representation of the band-gap reference current. The adjustable current source module is operably coupled to produce a process-independent band-gap current and a voltage representation of the process-independent band-gap current. The adjustable current source module produces the process-independent band-gap current based on a difference between the voltage representation of the band-gap reference current and the voltage representation of the process-independent band-gap current.
