This circuit with low-slip characteristics uses an operating system that is not very common today. The circuit can be designed with more modern operational and equivalent FETs.
This high impedance and low capacitance buffer employs a junction FET that can be BF245 or...
Found in 1980s documentation, this amplifier uses a symmetric source and the gain is given by the...
