Using an era germanium transistor, this 1960s circuit reverses the phase of relatively low frequency signals.
With this high voltage regulator, we can obtain 100 V outputs with currents up to 400 mA. The...
The CMOS 4046 integrated circuit is not very common today, consisting of a very efficient PLL for...
This circuit is from an old technical documentation, used to monitor the voltage of a 12 V...
