Abstract:  
This tutorial introduces the requirements and design techniques of ultra low power (ULP) analog CMOS integrated circuits, based on the framework of its application to implantable medical devices.  The talk has three parts. In the first part, the main characteristics and needs of implantable medical devices, particularly from the point of view of the analog circuit designer, are presented. The second part presents the field of ULP analog CMOS design by considering the aspects of device modeling, circuit design techniques and architectures. Finally, the last part, discusses perspectives in the fields of ULP analog CMOS and implantable medical devices.
