The kind of bagel that ruins lesser bagels for you.
Summary
This article explores the use of operational amplifiers for analog mathematical operations, moving beyond their typical amplification functions. It explains how op-amps can perform analog computing tasks like solving mathematical equations, despite the impracticality of large-scale analog computing due to error accumulation. The content focuses on practical applications, particularly in analog-to-digital converters, and provides accessible explanations of op-amp arithmetic operations for educational purposes.
Key quotes
· 3 pulledAnalog computing at a scale is wildly impractical because errors tend to accumulate every step along the way; nevertheless, individual techniques find a number of specialized uses, perhaps most prominently in analog-to-digital converters.
In today's episode, I'd like to talk about the use of operational amplifiers to do something other than amplification: to solve analog math.
The following assumes familiarity with op-amp arithmetics, explained in a more accessible way.
