The hybrid IC is not extinct. Hybrids can be tuned to give superior specifications, especially in drift over temperature and noise that cannot be reached with a high volume monolithic device. Apex ...

To sense animals moving I wanted to create a simple IR sensor that would trigger a monostable to generate a rather long pulse when an animal passed by. Further, while the animal remained in front of ...

An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...

Native SPICE elements that accurately replicate an op amp’s real-world behavior were nonexistent. A transconductance sourcing current from the rails and transitioning to a resistive state as the ...

When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper sibling for example, but still ...

Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital circuit is really just an analog ...
