See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...
