Abstract

In recent years the development of the applications in the field of telecommunications, data processing, control, renewable energy generation, consumer and automotive electronics determined the need for increasingly complex systems, also in shorter time to meet the growing market demand. The increasing complexity is mainly due to the mixed nature of these systems that must be developed to accommodate the new functionalities and to satisfy the more stringent performance requirements of the emerging applications. This means a more complex design and verification process. The key to managing the increased design complexity is a structured and integrated design methodology which allows the sharing of different circuit implementations that can be at transistor level and/or at a higher level (i.e.HDL languages).In order to expedite the mixed systems design process it is necessary to provide: an integrated design methodology; a suitable supporting tool able to manage the entire design process and design complexity and its successive verification.It is essential that the different system blocks (power, analog, digital), described at different level of abstraction, can be co-simulated in the same design context. This capability is referred to as mixed-level simulation.One of the objectives of this research is to design a mixed system application referred to the control of a coupled step-up dc-dc converter. This latter consists of a power stage designed at transistor-level, also including accurate power device models, and the analog controller implemented using VerilogA modules. Digital controllers are becoming very attractive in dc-dc converters for their programmability, ability to implement sophisticated control schemes, and ease of integration with other digital systems. Thus, in this dissertation it will be presented a detailed design of a Flash Analog-to-Digital Converter (ADC). The designed ADC provides medium-high resolution associated to high-speed performance. This makes it useful not only for the control application aforementioned but also for applications with huge requirements in terms of speed and signal bandwidth. The entire design flow of the overall system has been conducted in the Cadence Design Environment that also provides the ability to mixed-level simulations. Furthermore, the technology process used for the ADC design is the IHP BiCMOS 0.25 µm by using 50 GHz NPN HBT devices.
