Some Considerations on Openness of Design Information

Towards a sustainable society, design of artifacts must be optimized with limited resources on the earth while keeping our life. In order to realize it, I emphasize openness of design information. In this paper, I discuss needs for openness of design information and methods to realize it. I argue why design information should be open and what benefits will result by opening and sharing design i...

High-Speed PCB Design Considerations

The backplane is the physical interconnection where typically all electrical modules of a system converge. Complex systems rely on the wires, traces, and connectors of the backplane to handle large amounts of data at high speed. The communication between the various backplane modules depends on the inherent electrical characteristics such as impedance, capacitance, and inductance derived from c...

High Frequency Inverter Power Stage Design Considerations for Non-Magnetic Materials Induction Cooking

Recently induction cookers, which are based on induction heating principle, have become quite popular due to their advantages such as high energy efficiency, safety, cleanliness, and compact size. However, it is widely known that with current technology, induction cookers require the cookware to be made of magnetic materials such as iron and stainless steel. This is why a lot of cookware is lab...

Practical considerations for the design of cascade multi-bit high-frequency Σ∆ modulators

Recommendations are given for efficient design of highfrequency Σ∆ modulators using multi-stage (cascade) multi-bit quantization architectures. These cover from pure architectural aspects to cell design with special emphasis on the impact of circuit imperfections. Conclusions are validated by measurements on a 13-bit 2.2MS/s prototype fabricated in a 0.7μm CMOS technology.
