Wipe Out the Weakest Link with an AFE

摘要

Even though digital technology is creeping up the analog signal chain toward the source, analog signals will always be used to measure real-world analog data. An analog-to-digital converter (ADC) can be critical in moving analog data into digital processing, but you must examine the entire analog signal chain to get it right. An analog front end (AFE) can incorporate the entire analog signal chain as a kind of short cut, but let's examine the long way first.
