A CPU with a heat sink (e.g. Intel Pentium 4 and Intel Pentium dual core) is a challenging problem for EMC analysis. A Very Large Scale Integrated (VLSI) device was modelled using the Finite Element Method (FEM) frequency domain solver to obtain a 3D full wave solution. The electromagn...
The key module of the ADC, which is a 4-bit VCO-based quantizer, can convert the voltage signal into a frequency signal and quantize the corresponding frequency to thermometer codes at 400 MS/s. 展开 关键词: Practical, Theoretical or Mathematical/ clocks CMOS integrated circuits filters ...
银镯子在安检门中发出警报的原因是因为它含有金属成分,不过只要正确佩戴银镯子,就可以避免安检门报警的情况。 一、银镯子为什么会在安检门中发出警报? 有些人认为,银镯子会在安检门中发出警报是因为这种饰品本身就有一定的射频(Radio Frequency)标签,但这一说法并不正确。...
