Electronics Research

Researchers in electronics have interests in Analogue Circuit Design, Reliable Systems Design and Communications. This work is carried out in the following groups:

Electronic Circuit and Systems Design Research Group (ECSDRG)

The ECSDRG comprises two full-time academic staff, Dr Khaled Hayatleh (Head of Group), Professor John Lidgey, and Senior Visiting Research Fellow Dr Bryan Hart. The research focus is on high performance electronic circuits and systems and current projects include:

• investigating, designing and improving current feed back op-amps and op-amp linearisation
• design and analysing high frequency oscillators
• high frequency low noise amplifiers and mixers
• high accuracy voltage buffers
• high output impedance current source design
• low-voltage high-speed CMOS line driver for SerDes applications
• non-contact infra-red (IR) thermometers.

Currently there are 6 PhD research students in the Group. They are working on a range of analog and digital projects using both bipolar and CMOS technologies.

Communications Group

The Communications Group researches into a variety of topics based on mobile and modern high speed networks. We are particularly interested in three main areas:

• The transmission of multimedia data over 3G and future 4G mobile networks. Our work is mainly aimed at improving the quality of service and enhancing the efficiency of these networks through intelligent manipulation of transmission parameters and enhanced cross-layer communication.
• Mobile ad-hoc networks. This work is concerned with the performance of routing protocols and the associated quality of service and security issues
• Voice over IP. It is expected that a large percentage of voice calls will be carried over IP networks within the next decade and this research is examining issues of quality and multiple communication groups.

The communications group make use of OPNET software. Staff in the group are Dr Maaruf Ali, Dr Peter Ball and Dr Geoff Childs.
