This circuit with 1% regulation aims at replacing mercury cells. We found it in a 1967 documentation. Transistors can be replaced with modern equivalents.
In the figure we show the typical configuration of a shared line using a twisted pair where the...
We found this digital CMOS circuit in a documentation from the 90s. The circuit generates signals...
This tuning-free circuit was found in an old operating amplifier manual. The setting can serve as...
