Abstract: With the increasing demands for signal transmission rates or resolution in fields such as wireless communication, radar, satellite communication, and optical communication, the modulation formats used have become increasingly complex, and the signal bandwidth has also widened. Modern real-time oscilloscopes, due to advancements in chip and material technology, can provide real-time measurement bandwidths of … Read more
Mark as Favorite Read Good Articles Daily As a PCB design engineer, it is essential to possess knowledge about high-speed signals. High-speed signals are typically found in various parallel buses and serial buses. Understanding what a bus is will help you determine its speed and start routing. Bus A bus is a shared physical pathway … Read more
As the working frequency of DSP continues to increase, the design of power and ground has become increasingly important in high-speed DSP systems. This also raises higher requirements for electronic engineers. A reasonable design of power and ground not only affects system performance but also directly impacts the stability and reliability of the system. Therefore, … Read more
01 Power Layout and Wiring Digital circuits often require non-continuous current, which can cause surge currents in some high-speed devices. If the power routing is long, the surge current can lead to high-frequency noise, which can then couple into other signals. In high-speed circuits, parasitic inductance, parasitic resistance, and parasitic capacitance are inevitable, so this … Read more
