This small signal amplifier circuit was found in Motorola's 1969 documentation. The FET and the transistor can be of any type and is battery powered since the consumption is very low.
This circuit compensates for losses in pre-amplified audio or tone control stages. The circuit can use...
Found in the Encyclopedia of Electronic Circuits volume 5 from 1995, this circuit uses a...
This is a bridge for the measurement of low value resistances and high values too. The circuit...
