This amplifier with old germanium transistors is from a 1957 documentation. The power is a few hundred milliwatts and the transformers are common types of driver and output of the time.
From an input signal, and using an unusual current source, this circuit generates a ramp, that is, a...
This circuit doubles and reverses the polarity of voltage Ve which can be between 5 and 15 V. The...
Using an operational with FET this circuit presents excellent gain and does not need a symmetric power...
