Embedded RTOS in the end “real time” where?

Embedded RTOS (Real Time Operating System) has made a big splash in recent years. Embedded MCU, has long been out of the main frequency of only 8MHz era, now embedded controller chip, the main frequency can be as high as 600MHz, and ordinary MCU can easily run at 64MHz. not only the main frequency of the qualitative leap, and Arm Cortex-M series of MCUs, the early stage of the kernel design has also been added to support the RTOS of the native kernel instructions. However, although RTOS is called a “r....

Should I lay copper under the inductor? PCB Design Guidelines for Low EMI DC/DC Converters

Every switching power supply is a broadband noise source. Therefore, integrating a DC/DC converter in an automotive circuit board network into an automotive control unit while still meeting the EMC requirements of the automotive original equipment manufacturer (OEM) can be a daunting task. Typically, noise from DC/DC converters and other high-speed circuits radiates through the connected cables, which provide an effective antenna path for the noise. To block this potential radiation path, filter circuits ar....

Constant current source application and multiple circuit design details

A constant current source is a power supply that can provide a constant current to a load, so constant current sources have a wide range of applications and are essential in many cases. For example, when charging a battery with the usual charger, the charging current will be reduced accordingly as the battery terminal voltage gradually increases. In order to ensure constant-current charging, the output voltage of the charger must be increased at any time, but the use of constant-current source charging can ....

DC/DC Buck Circuit “Ground Bounce” Principle and Solution

In electronic design, DC/DC step-down circuits are a common type of circuit used to convert higher DC voltages to lower DC voltages. However, this type of circuit often encounters a tricky problem during operation - Ground Bounce. Ground bounce, also known as ground bounce, is a transient voltage fluctuation at the ground node caused by a rapid change in current. This phenomenon not only affects the performance of the circuit, but also may produce electromagnetic interference (EMI), thus affecting the stabi....

How to effectively reduce static electricity damage to electronic components?

In the winter, static electricity on electronic components and equipment damage can not be ignored (although it is now summer), the production line every year to increase the investment in anti-static measures. So, how should we effectively reduce and prevent static electricity damage to electronic components? In the SMT process, electrostatic discharge will cause damage to electronic components or failure, with the increase in IC integration and components of the gradual shrinkage, the impact of static ele....

Difference between active crystal oscillator and passive crystal oscillator

In the field of electronic engineering, crystals (crystal oscillators) are one of the key components that ensure the stable operation of electronic devices. They utilize the inherent frequency characteristics of the crystal material to generate a stable clock signal, providing a time reference for the system. Crystals are divided into two main categories: active crystals and passive crystals. Although both are used to generate clock signals, but they are in the structure, principle of operation, performance....

DC Power Supply True RMS Measurements

The ripple and noise of a DC power supply are important parameters for evaluating the quality of the power supply, and they reflect the instability and interference of the power supply output. Large ripple or noise may lead to unstable system operation, increased sensor error, distortion of analog signals, and other problems. Therefore, it is very important to properly measure and evaluate ripple and noise levels when designing and selecting power supplies. This article will describe how to test DC power su....
