This circuit is from the Motorola Linear Databook of 1990 and can be implemented with other operational amplifiers. The power supply must be symmetrical.
This circuit uses two transistors, the low noise BC549. Its quality is very good and it has a...
This simple circuit was found in an old documentation. The transistor can be changed according to the...
This complementary-output amplifier can be used to source a good qualuty signal to high impedance...
