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
A design is needed for an isolated circuit that outputs a variable voltage of 0~12V, with the isolated side powered by 12V. There are no specific speed requirements for the output voltage. The accuracy is not particularly critical, as it just needs to stabilize once set. The design uses an optocoupler driven by the PWM … Read more
NAD was established in 1972, and over fifty years later, it continues to be at the forefront of product design and philosophy, bringing us many surprises through new technologies, such as this little black box we are discussing today—the NAD C700. 1. Usage Scenarios Overall dimensions: 218 x 96 x 266 mm. Upon first seeing … 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
With the rapid development of the Internet of Things, remote healthcare, and autonomous driving, the demand for high-speed signals in modern society is increasing. Currently, the signal frequency in electronic system design is generally above 100MHz, and high-speed data transmission lines face challenges in signal integrity. During transmission, signals are prone to issues such as … Read more
