This precision reference circuit was found in documentation from the 1980s. It applies to other operational amplifiers. The power supply must be symmetrical.
Found in old documentation about neon lamps, this circuit produces very low frequency signals that...
In the figure we show how to use a small Hartley oscillator as a continuity tester. The component...
In the figure we have a interfacing circuit of TTL logic as CMOS logic using a 6N139 optical...
