ABSTRACT
Design guidelines for output buffers with adaptive slew rate control are presented in this paper. By adapting the output driver strength against supply voltage variations it is possible to meet the slew rate requirements as well as to commit with Electromagnetic interference (EMI) compliance levels for an wide supply voltage range. An output buffer based on the proposed methodology was designed and fabricated using a 0.25um SMARTMOS process technology.
