This configuration found in GE documentation from the 90s, can also be seen elsewhere in this section. It can operate with voltages from 1 to 6 V and consumes only 6 mW at 1.5 V.
In this block we have a configuration of the most common ones in which some additional elements, which...
We found this circuit in documentation from the 1980s. The transistors can be the BC558 and the...
This circuit found in a 1993 Electronics Hobbyst Handbook has a very simple configuration that can be used on...
