Abstract

In this paper an automation tool is proposed for OTA designs. The core of the tool is a combination of a mathematical tool and a circuit simulator. The automation tool contains four libraries: OTA topologies, technology parameters, performance limits and design constraints. Design of typical OTA topologies can be implemented in three fabrication technologies. The user introduces OTA specifications and the automation tool looks for the best OTA structure considering the cheapest fabrication technology available in the library, and delivers a sized circuit that fulfills design specifications. Our automation tool is illustrated by a complete design flow of an FDFC with CMFB OTA in AMIS 0.5 mum CMOS technology.
