is sufficient, the resistance is small, and the current is large. 3. for High-Speed Circuits, excessive pull-up resistance may smooth the edge. Comprehensive Consideration The preceding three points are usually selected from 1 K to 10 K. Similar to the drop-down Resistor The selection of the pull-up and drop-down resistors should be set based on the characteristics of the switch and the input characteristics of lower-level

Magnetic BeadsIt is designed to suppress high-frequency noise and Spike interference on signal lines and power cables, and also to absorb electrostatic pulses. Magnetic Beads are used to absorb ultra-high frequency signals, such as RF circuits, PLL, oscillating circuits, and ultra-high frequency memory circuits (ddrsdram, Rambus, etc.). They need to be added to t

Source: Power Supply NetworkKeywords: MOS Structure switch Drive Circuit When using MOS to design a switching power supply or motor drive circuit, most people will consider the mos on-resistance, maximum voltage, maximum current, and so on. Many people only consider these factors. Such a circuit may work, but it is not excellent. It is not allowed as a formal product design. The following is my summary of the basis of the mos and MOS driving circuit. I have referred to some materials, not all or

First, the FPGA can do two types of chips, digital circuits and microprocessors Microprocessors generally and SOPC on-chip systems (that is, the microprocessor and some on-chip peripherals are integrated into a chip) to do together, such as Nios-ii, and then again Digital circuits are divided into: Combinational logic circuits (

In the first year as an electronic engineering student, you've been told repeatedly that electrostatic discharge (ESD) is a phenomenon of electrical transients and poses a serious threat to electronic circuitry. The most common reason for electrostatic generation is that the friction between the two different materials causes the charge to accumulate on the friction surface. The use of handheld and wearable electronic devices continues to grow, involving one of the friction surfaces that are hum

Hardware: Microprocessor (MPU, up ):A device composed of a computer's processor and a controller integrated into a chip is called a microprocessor, also known as a central processing unit (CPU, central processing uint). a cpu is the brain of a computer system, various logical and arithmetic operations, program execution, and generation of various control signals are implemented. Other components in the computer system are coordinated under the command of the CPU. Microcomputer:The CPU (including

What are the differences between VCC, VDD, and VSS in electronic circuits? I. Explanation VCC: c = circuit indicates the circuit, that is, the voltage of the access circuit; VDD: D = device indicates the working voltage inside the device; VSS: S = series indicates the public connection, which usually refers to the public grounding terminal voltage of the circuit. Ii. Description 1. for digital circuits

1. Dip dual-row direct insert Encapsulation Dip (dualin-line package) is an integrated circuit chip encapsulated in the form of Dual-row direct insertion. Most small-and medium-sized Integrated Circuits (IC) use this encapsulation form, generally, the number of pins cannot exceed 100. The CPU chip in dip package has two pins and needs to be inserted into the chip socket with dip structure. Of course, it can also be directly inserted into the circuit

applicable to high-frequency circuits, because at low frequencies, they basically maintain the complete characteristics of inductance (including resistance and resistance components), which may cause slight loss on the line. At high frequencies, it basically only has the resistance component (J ω L), and the resistance component will increase as the frequency increases. For example, some RF circuits, PLL,
