1. Selection of pull-up resistor for MCU You can see that when the resistor R1=10k in the reset circuit, RST is high level, and when R1=50, RST is low level. It is obvious that when R1=10k, it is wro...
This article explains what role PLL plays as LO in wireless communication systems, the principle of fractional frequency division in its operation, the principle of Sigma-Delta fractional frequency di...
The static part of the common source amplifier circuit is shown in the figure. In the figure, R1 is connected to a 5W resistor. When the static working point is adjusted by 12V, the GS voltage is arou...
Ensuring the reliability of communication and meeting the stringent requirements of service quality are important issues in short-range wireless communication systems. The key characteristics of short...
