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 amplifier was found in an 80s component manual. The circuit can be used for media recovery....
This is a bridge for the measurement of low value resistances and high values too. The circuit...
This digital mixer uses CMOS integrated circuits. The circuit was published by us in a magazine...
