Although it uses a dual-channel FET, which is hard to find today, this circuit was released in a Radio Electronics issue in April 1986. It serves as a signal booster for a wide range of frequencies.
This interface was found in a Modern Electronics magazine from 1990. Although the circuit is...
We found this circuit in a 1981 publication. We applied an audio signal, for example, a music...
In a voltage follower, the voltage gain is unitary, the input impedance is very high, and the...
