In the figure we have an IF amplifier step using a MOSFET. The circuit was found in a 1980s documentation, intended for FM receivers of the time.
This circuit converts the voltage from small fixed sources of 6 V or 12 V into 3 V for powering...
This stage was used in old audio ampliiers and radios from the 1950s and 1960s. It uses one of the...
This useful benchtop power supply uses a single LM350 integrated circuit as a regulator. The...
