Basic Concepts Returning … Read more
Source:Failure Analysis and Reliability Testing of Semiconductor Components Author:Chip Failure Analysis With the prosperity of modern electronic products, chips have become an indispensable component of various electronic devices. Although chips may sound somewhat abstract, they can actually be categorized into different types. Let’s explore some common types of chips together. 1. Microcontroller (MCU) A microcontroller … Read more
Introduction to ADC The STM32F103 series has 3 ADCs with a precision of 12 bits, and each ADC can have up to 16 external channels. ADC1 and ADC2 both have 16 external channels, while ADC3 generally has 8 external channels. The A/D conversion of each channel can be executed in single, continuous, scan, or interrupt … Read more
Focused and dedicated, stepping onto the international stage Written by|Little Medicine Monster The latest generation of anti-HER-2 ADC drug developed by Hengrui, SHR-A1811, is often jokingly referred to as the domestic alternative to DS-8201 due to its similar structure. However, strength will eliminate all rumors. Results from early clinical studies released by AACR this year … Read more
Overview In the design of high-speed analog signal chains, the layout and routing of the printed circuit board (PCB) need to consider many options, some of which are more important than others, while others depend on the application. The final answers vary, but in all cases, design engineers should consider the overall picture rather than … Read more
Acquisition Time Acquisition time is the time required for the sample-and-hold circuit to stabilize the sample capacitor voltage within 1 LSB range of the new input value after releasing the hold state.The formula for acquisition time (Tacq) is as follows: Aliasing According to the sampling theorem, input signal frequencies above the Nyquist frequency are referred … Read more
1 ADC Chip Debugging Understanding the function of the ADC chip: the Analog-to-Digital Converter (ADC) converts analog voltage into a digital signal. Connect the voltage line to the ADC’s measurement pin, and the ADC module will detect this voltage and automatically convert it to a number. Reading this number gives us the relationship between the … Read more
In Simple Terms: The AD7606 is a 16-bit multi-channel synchronous sampling ADC, widely used in many acquisition systems. It has been the most utilized ADC since I started working. Even though I have changed jobs twice, this chip remains a key component in the products of every company I have worked for. Imagine if you … Read more
Hello everyone, I am Yi. Let’s continue with the design and selection of current detection circuits. In the previous article, we analyzed the resistance method for measuring current, and found that the limitation of the resistance method is that it introduces power loss, making it unsuitable for measuring large currents. For measuring large currents, Hall … Read more
