—A modification of stacked spiral inductors increases the self-resonance frequency by 100% with no additional processing steps, yielding values of 5 to 266 nH and self-resonance frequencies of 11.2 to 0.5 GHz. Closed-form expressions predicting the self-resonance frequency with less than 5% error have also been developed. Stacked transformers are also(More)
The proliferation of 2.4GHz wireless standards such as Bluetooth and IEEES02.llb makes it desirable to realize low-power, compact transceivers capable of interoperability between frequency-hopping and direct-sequence systems. While Bluetooth requirements for receiver sensitivity and phase noise and transmitter linearity are relatively relaxed, those of(More)
The Distinct Element Method (DEM) is a numerical method for the simulation of the behaviour of media consisting of discrete particles, and is widely used for process optimization in the food and pharmaceutical industries. The DEM is very computationally expensive, but has properties that make it amenable to acceleration by reconfigurable computing. This(More)
The Discrete Element Method (DEM) is a numerical model to describe the mechanical behaviour of discontinuous bodies. It has been traditionally used to simulate particle flows (e.g. sand, sugar), but is becoming more popular as a method to represent solid materials. The DEM is very computationally expensive, but has properties that make it amenable to(More)
