IC Insights released the 2021 edition of the McClean report in January this year, which pointed out that many semiconductor companies are rushing to the manufacturing processes of 7nm and 5nm nodes, ...[Details]
With the continuous improvement of the requirements of intelligent building security systems and the continuous improvement of people's safety awareness, indoor anti-theft has gradually attracted p...[Details]
For electric vehicles, the battery life of the vehicle is also a concern for everyone. When the vehicle is in use, people may worry that the battery life may be inaccurate due to sudden driving, resu...[Details]
Bandwidth is defined as the point on the amplitude versus frequency diagram at which the measurement system is 3dB below the reference level, as shown in Figure 4.7, which illustrates the response ...[Details]
Recently, researchers from Karlsruhe Institute of Technology (KIT) in Germany and the University of Toronto in Canada have successfully used silicon nanocrystals to create efficient silicon-based...[Details]
Take SPI as an example: (As for why those structures are configured in this way, you can find it in the official information of STM32 and related learning books. I will not say more here, but just gi...[Details]
First, let's look at two waveforms: The first is the waveform of the MOS tube drain (with a load of 500W). It can be seen that the spike caused by the leakage inductance has disappeared (without an...[Details]
According to foreign media reports, Diodes Incorporated of the United States has launched two precision operational amplifiers (op-amps) DIODES™ AS2376Q and AS2333Q for different signal frequency sce...[Details]
According to Jiwei.com, it is well known in the industry that power semiconductors are used in all power electronics fields, and the market is mature, stable, and growing significantly. The developme...[Details]
I started to get involved in embedded systems by learning microcontrollers, so I always felt that I should start from the hardware and then move on to the drivers. This learning process made it eas...[Details]
