Summary on Grant Application Form |
|
The project aims to investigate the theoretical and experimental performance of switched current (SI) wave elliptic filters and equalisers based on direct and inverse Bruton transformations. The application of Bruton transformations in the design of wave filters has recently been proposed and shown to yield significant reduction in the SI circuit complexity when compared with previously reported results. The first aim of the research is to develop analytical models of the filter basic building blocks taking into consideration the SI cells non-ideal parameters, in order to study and minimise their effects on the filter frequency and distortion performance. The second aim is to design and fabricate, using a standard digital CMOS process, a high frequency SI lowpass elliptic filter with group delay equalisation to verify the theoretical investigations. To explore performance trade-offs of the various SI filter design methods, the third aim of the research is to carry out a comparison between Bruton transformations and ladder based elliptic filters in terms of sensitivity, THD, transistor count and component spread. The final aim is to develop a CAD tool, in which a Bruton transformation SI wave elliptic filters and equalisers can be synthesised directly from a frequency specification.
