Separated by strait, united by problems. Some aspects of microelectronics development in China and Taiwan The People’s Republic of China (PRC) and the Republic of China (Taiwan) relied on the development of microelectronics with a slight difference in time and achieved impressive results. There is much in common between the PRC and Taiwan but differences remain due to the size of economies, the population size, the availability of natural resources and traditions.

Determination of effective parameters of heat transfer layers in multi-layer printed circuit boards The article presents the mathematic simulation study on determination of maximum thickness of heat transfer layers in multi-layer printed circuit boards of electronic modules. Further increase of the thickness of heat sink layers becomes unreasonable due to an excessive increase in the mass of these layers and the lack of significant decrease of the temperature of the heated components.

Expansion of microwave ADC’s dynamic range using logarithmic amplifiers High-frequency signal processing with a wide dynamic range is one of the priority tasks in the development of modern communication systems. The higher the input signal frequency the higher the conversion frequency. The authors proposed the design consisting of logarithmic amplifier and ADC that expands the dynamic range of the signals processed by ADC while maintaining a constant specified relative error.
