A method of shrinking an existing mixed signal IC containing analog and digital circuitry includes the step of first enlarging (growing) the analog circuitry by a first ratio, followed by the step of recombining the enlarged analog circuitry with the existing digital circuitry and, then, optically shrinking the recombined analog and digital circuits by a second ratio. In one embodiment the analog circuits are enlarged by a factor that will offset the subsequent optical shrink. As a result, the analog circuitry is essentially unchanged on silicon, while the digital circuitry will be smaller, thereby making the overall chip smaller.
