Introduction: The AD9880 integrates an automatic offset function. The automatic offset function works by monitoring the output of each ADC during the clamping period and calculating the required offse...
Question: When using the official routine to perform AD sampling, it is found that the DC sampling value is very jittery, and only the value on the hundredth place does not jitter.
Solution: 1. The AD...
As we all know, analog circuits are difficult to learn. For the most common transistor, when we analyze it, we must first analyze the DC bias and then the AC output voltage. It can be said that determ...
