The IP.com Prior Art Database
A technique and apparatus for correcting systematic offset between a mirror voltage and an output voltage in a current mirror is disclosed. A correction loop incorporates an operational amplifier coupled to the output and mirror voltage of the current mirror. The operational amplifier feeds back to regulate a supply voltage of the current mirror, which forces the mirror voltage of the operational amplifier toward that of the output voltage.
