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
