Dr Ronan Farrell - Research

NUI Maynooth My past experience has been in the field of non-linear discrete-time dynamics and in CMOS silicon circuit design. This combination combines constructively at the digital analog interface where the signals can be considered as discrete-time continuous valued signals.

My current research area is still in this area. My topics of interest in this area are:

Oversampling techniques for improving performance and robustness of systems.

Data Converters, both analog-to-digital and digital-to-analog converters. My particular interests are in low power high resolution low frequency converters and medium resolution converters at high speeds which would be suitable for Radio-Frequency applications.

Radio-Frequency Applications are also of an interest as it is possible to take the benefits of high frequency digital logic and use this to replace some of the analog components in RF applications. This should make the system easier to design and more robust to component parameter variation. In particular it is possible to add flexibility to the design, for example software radios which have a common analog front-end but with flexibility of transmission format provided by digital logic.
