To learn embedded, you need to understand hardware knowledge, including single-chip microcomputer, ARM, FPGA, etc. Different hardware has different characteristics, and you need to understand their corresponding characteristics to be beneficial to operating applications. So what are the differences and characteristics of MCU, ARM, FPGA, and embedded?   Features of MCU:   1. Due to […]

Analog chip Analog chips mainly include power management chips and signal chain chips. Among them, the power management chip is a chip that is responsible for the conversion, distribution, detection and other power management responsibilities of electric energy in the electronic equipment system. It is mainly divided into AC-DC AC-DC conversion, DC-DC DC and DC […]

Amplifier task is to amplify the weak electrical signal from the signal source (from the mixer in the professional audio system) to drive the speaker to produce sound. It can also refer to other devices that perform power amplification. The function of the power amplifier is to amplify the weak signal from the sound source […]

The circuit diagram is one of the basic skills that electronics engineers must learn. This article combines the classic integrated circuit data related to regulated power supply, DC to DC conversion power supply, switching power supply, charging circuit and constant current source to provide engineers with the most fresh circuit diagram reference materials.   First, […]

First, what is IGBT? IGBT (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate field effect transistor), and has MOSFET The advantages of both the high input impedance and the low turn-on voltage drop of the GTR. The […]

On August 24, ADI officially announced that the acquisition of Maxim by ADI has obtained anti-monopoly approval from the State Administration for Market Regulation of China!   So far, the transaction has obtained all necessary regulatory approvals. ADI and Maxim expect that the transaction will be completed on or about August 26, 2021 after meeting […]

integrated circuit Integrated circuit (Integrated circuit) is a kind of miniature electronic device. It uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit on a semiconductor substrate, and then encapsulate them in a tube. Inside the shell, a miniature structure with the required circuit […]

Two conductors close to each other sandwich a non-conductive insulating medium between them, which constitutes a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on one conductive plate to […]

Transistor is a solid semiconductor device (including diodes, triodes, field effect transistors, thyristors, etc., sometimes referred to as bipolar devices), which has multiple functions such as detection, rectification, amplification, switching, voltage stabilization, signal modulation, etc. . As a variable current switch, the transistor can control the output current based on the input voltage. Unlike ordinary […]

1. Detect a small capacitor below 10pF. The capacity of a fixed capacitor below 10pF is too small. Use a multimeter to measure it. Only qualitatively check whether it has leakage, internal short circuit or breakdown. When measuring, you can use the multimeter R×10k block. Use two metal meter bars to connect the two pins of […]
