FREQUENCY MULTIPLIERS (HARMONIC GENERATORS) are special class C amplifiers
that are biased at 3 to 10 times the normal cutoff. They are used to generate a frequency that is a multiple
or harmonic of a lower frequency.
A BUFFER AMPLIFIER decreases the loading effect on the oscillator by reducing the interaction
between the load and the oscillator.
