1. Efficient Reconfigurable Multipliers Based on the Twin-Precision Technique
Abstract : During the last decade of integrated electronic design ever more functionality has been integrated onto the same chip, paving the way for having a whole system on a single chip. The strive for ever more functionality increases the demands on circuit designers that have to provide the foundation for all this functionality. READ MORE

2. Symmetric varactor frequency multipliers
Abstract : This thesis describes heterostructure barrier varactor (HBV) frequency multipliers for millimetre and sub-millimetre wave applications.The basic principles of HBVs are explained. Starting from basic varactor theory, an equivalent circuit model for HBVs is presented. READ MORE

3. Fabrication of Integrated HBV Multipliers for THz Generation
Abstract : The main objective of this licentiate thesis is to demonstrate silicon integrated HBV frequency multipliers for THz generation with RF performance comparable with InP technology. The choice of silicon is motivatedby better thermal and mechanical properties, cost and ease of integration compared to III-V semiconductor substrates. READ MORE
