This voltage follower or amplifier with unit gain uses an unusual operational amplifier nowadays. The circuit can be implemented to use modern operationals. The power supply must be symmetrical.
Found in a 1980’s documentation, this circuit must have its signal applied to an amplifier stage. The...
