Experiences on analog circuit technology migration and reuse

Abstract

This work deals with two aspects of the reuse and redesign of analog circuits. First, a method for technology migration of analog circuits, recently proposed by Galup-Montoro and Schneider (Proc. SBCCI2000, pp. 89-93, 2000), is validated experimentally in the redesign of a Miller OTA from a 2.4 /spl mu/m technology to a 0.8 /spl mu/m technology. In addition, the impact of the method on performance aspects of analog circuits not covered in the original proposal (slew rate and current mirror frequency response) is studied. As a second mechanism for allowing the reuse of analog circuits, the feasibility of the application of the reference bias current as a tuning parameter to customize the performance of an existing design to suit different applications is demonstrated
