This detector with ultra-low deviation was found in an American documentation from the 90s. Operational amplifiers are from that time. The power supply must be symmetrical.
The use of field effect transistors in this circuit improves its performance. This configuration is from a...
This is a simple source indicated for powering low voltage projects on the bench. The circuit is...
This circuit was found in a 1969s American documentation. With modern components, it can be used...
