Silicon-germanium (SiGe) heterojunction bipolar transistor (HBT) BiCMOS technology has established a strong foothold in the communications marketplace by offering a cost competitive solution for a myriad of products. SiGe BiCMOS technologies currently address various applications ranging from 0.9-77 GHz. At the heart of this success is the ease of(More)
With the increase in cost and resources constraints experienced by many tertiary institutions globally, the pressure to find alternative methods to deliver teaching and assessment increases. Whilst mindful of the learning experience of the individual, the need to manage the numbers, resources and assessment provide an administrative overhead and headache to(More)
Silicon-germanium (SiGe) BiCMOS technology has advanced in many areas. In this paper, we discuss and illustrate the key device design issues for SiGe BiCMOS HBTs suitable for wireless power amplifier applications. The experimental results for high-breakdown SiGe HBTs built in several generations of BiCMOS technology are presented with focus on the 0.5 /spl(More)
An internet, browser-based, computer-supported learning system was designed and built by the MSIS Department to serve primarily as an assessment vehicle for business students. Now in its second year of operation it has migrated across computer platforms and been completely redesigned to become a university resource. Hundreds of students use CSL daily. This(More)
If sufficient attention is not paid to the information models on which Learning Platforms are based the ability to deliver rich functionality is hindered. This paper describes the issues and records the experiences of the Cecil development in confronting this and the benefits that have been gained. This system, which has been evolving for 7 years, has been(More)
The increasing complexities of modern networks coupled with the popularity of multimedia applications have placed higher demands on network managers. This paper reviews the main requirements and challenges for effective management of multimedia networks, presents a case study of a thin-client-based multimedia system called CSL (Computer-supported Learning(More)
Included in the New Zealand Government’s green paper “ A Future Tertiary Education Policy for New Zealand is the intention to put in place common quality standards, standard methods for reporting programs of study, and a national system to record all students registered in any paper at any tertiary institution. Through the National Qualifications Framework(More)
National and international standards for professional groups may become a dominant and governing force as internet-based professional training becomes universally accepted. Educators and trainers will be expected to demonstrate the relevancy of their programmes in the context of bodies of knowledge that have a wide acceptance. Universities will feel the(More)
