—This paper discusses high-performance planar suspended inductors for hybrid integration with microwave circuits. The inductors are fabricated using a silicon surface microma-chining foundry process and assembled using flip-chip bonding. The silicon substrate is removed, leaving a metal inductor suspended 60 m above the microwave substrate, thus reducing(More)
The change in the energy barriers for the heterogeneous reduction of pyruvate decarboxylase (PDC) relative to its coenzyme, thiamin pyrophosphate (ThPP), was determined experimentally using square wave voltammetry (SWV) to be 5.3 kcal/mol. These results are in agreement with those of reaction rate acceleration provided by thiamin-dependent decarboxylases(More)
Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. In recent years, there has been a great deal of interest in MEMS reconfigurable circuits for applications in miniaturized multifunctional microwave(More)
This paper presents work towards heterogeneous integration of high-efficiency power amplifiers (PAs) with tuner and biasing circuits implemented with micro-electro-machined elements. The PAs operate in switched mode with over 70% efficiency at X-band. Many such switched-mode amplifiers are used as the active portion of spatial power combining antenna(More)
