How clock signal is generated in microcontroller?
Whether it is a single-chip microcomputer or a microprocessor, their core is a large-scale sequential logic circuit, and the power driving the sequential logic circuit is an accurate and stable clock source-don’t underestimate the attributive “accurate and stable”,
How do you know if a capacitor is bad on a circuit board?
There are tens of thousands of small electronic components in the circuit. Therefore, when our circuit design is improper or the voltage is unstable, it is easy to cause circuit failure
What Is Controlled Impedance in PCB?
PCBs have the unique job of carrying electric signals between connecting parts. These electronic signals are necessary for a device to perform its function, and it won’t work without them. These signals travel through signal traces that run through the PCB.
Key Points of Common Interface Types in PCB Design
We know that there may be some problems in the data exchange between the various sub-modules of the circuit system that cause the signal to fail to “flow” normally and with high quality.
Signal Ground VS Chassis Ground
The power ground is mainly for the path of the power loop current. Generally speaking, the current flowing through the power ground is relatively large,
Switching Power Supply: Uses Advantages and Working
A power supply is an electrical device that converts the electric current that comes from a power source to the voltage value necessary for powering a load, like a motor or an electronic device.
How to Optimize Switching Power Supply Layout
In a successful power supply design, power supply layout is one of the most important links. However, everyone has their own opinions and reasons for how to do this. The truth is, many different
