Abstract
A method for correcting digital gain error for a digital code includes receiving the digital code, generating a random number, adding a first dither to the digital code, in which a magnitude of the first dither is determined based on the random number, performing an operation on the digital code including the added dither with a factor to generate a scaled digital code, and subtracting a second dither corresponding to the first dither from the scaled digital code.
