1. First, let’s discuss open-drain output and push-pull output First, watch the video explanation: The following video is from Guo Tianxiang Push-Pull Output Structure and Principle: A push-pull output circuit consists of two complementary transistors (usually an NPN transistor and a PNP transistor). In this structure, when the input is high, the upper transistor (like … Read more
When designing PCBs, it is evident that the routing process is indispensable. The rationality of the routing not only determines the aesthetics of the PCB and its production costs but also reflects the performance of the circuit and its heat dissipation capabilities, as well as whether the performance of the components can be optimized. This … Read more
Definition of High-Frequency PCB High-frequency boards refer to special circuit boards with electromagnetic frequencies that are relatively high, used in the fields of high frequency (frequency greater than 300MHz or wavelength less than 1 meter) and microwave (frequency greater than 3GHz or wavelength less than 0.1 meter) PCBs. They are produced using standard rigid circuit … Read more
Technical Field: Electronic devices, particularly those with rigid-flexible circuit boards. More specifically, it relates to rigid-flexible circuit boards with signal lines and grounding areas on both sides and below some conductive layers in the flexible circuit board area to reduce impedance variation. Background Technology Overview: With the increasing integration of electronic devices and the popularity … Read more
