This circuit, which can use the 4011 or 4001, was found in documentation from the 90s. The load depends on the transistor used, and the power supply must be isolated.
This is a traditional configuration of a transistor amplifier with complementary transistors that can be...
This circuit was obtained in the publication 101 Electronics Projects of 1979. The circuit can be...
This circuit is from the 80s. The integrated circuit used is uncommon as is the transducer....
